  @article{MARTI2024100145, abstract = {Higher magic angle spinning (MAS) frequencies than currently available are desirable to improve spectral resolution in NMR and EPR systems. While conventional strategies employ pneumatic spinning limited by fluid dynamics, this paper demonstrates the development of an optical spinning technique in which vacuum quality dictates the maximum achievable spinning frequency. Using optical traps, we levitated a range of micron-sized samples. Under vacuum we achieved optical rotation of a single ∼10 μm diameter particle of vaterite at several mbar up to hundreds of Hz and of 20 μm diameter SiO2 particles at ≤10−2 mbar at several kHz. At ambient conditions, we optically levitated γ-irradiated alanine particles of 20–50 μm diameter. Additionally, using a single chip EPR detector operating at 11 GHz, we measured the EPR spectrum for a 30 μm γ-irradiated alanine particle in contact with the chip surface (i.e., without optical levitation) in a single scan lasting 92 s. These observations suggest that a γ-irradiated alanine particle having a diameter in the order of 30 μm is a promising candidate for our aim of demonstrating the first magnetic resonance experiment on optically levitated samples. Furthermore, we discuss strategies, limitations, and the potential of implementing MAS with optical traps for NMR and EPR.}, author = {Marti, Lea and {Şahin Solmaz}, Nergiz and Kern, Michal and Chu, Anh and Farsi, Reza and Hengel, Philipp and Gao, Jialiang and Alaniva, Nicholas and Urban, Michael A. and Gunzenhauser, Ronny and Däpp, Alexander and Klose, Daniel and Anders, Jens and Boero, Giovanni and Novotny, Lukas and Frimmer, Martin and Barnes, Alexander B.}, doi = {https://doi.org/10.1016/j.jmro.2023.100145}, issn = {2666-4410}, journal = {Journal of Magnetic Resonance Open}, pages = 100145, title = {Towards optical MAS magnetic resonance using optical traps}, url = {https://www.sciencedirect.com/science/article/pii/S2666441023000535}, volume = 18, year = 2024 }

  @inproceedings{10067623, abstract = {Electron paramagnetic resonance (EPR) spectroscopy is a powerful technique that uses the spin of an unpaired electron as a nanoscopic probe inside a molecule to extract information about its chemical structure and composition as well as its surroundings via small changes in its resonance frequency, see Fig. 21.4.1 (left). EPR has applications in studying and monitoring a wide range of materials, starting from defects in semiconductors over free radicals in the blood to metal catalysts in hydrogen fuel production. EPR measurements are typically performed in moderate static magnetic fields around 0.3T, corresponding to EPR frequencies around $9\mathsf{GHz}$. This combination of field and frequency is commonly used due to the relative ease of generation of 0 $3\mathsf{T}$ magnetic fields with sufficient homogeneity as well as the required $9\mathsf{GHz}$ frequency signal. However, access to higher frequencies and fields is strongly desirable due to higher spin polarization (with corresponding increased signal amplitude), higher spectral resolution, which allows, e.g., the determination of electronic and geometric structures of active centers in enzymes, and access to higher energy electronic transitions, such as those found in metal complexes or materials interesting for antiferromagnetic spintronics, explaining the ongoing research towards high-frequency EPR (HFEPR) with operating frequencies beyond $90\mathsf{GHz}$. Here, another strong driver of HFEPR is the field of dynamic nuclear polarization (DNP), a method that can be used to boost the relatively poor sensitivity of nuclear magnetic resonance (NMR) by transferring the intrinsically higher electron polarization to the nuclear spins. Today, there are only a few commercial HFEPR-based DNP spectrometers on the market, with the most popular ones operating at an EPR frequency of $263\mathsf{GHz}(9.4\mathsf{T})$, corresponding to a proton NMR frequency of $400\mathsf{MHz}$. These instruments use gyrotron as the source for the mm-wave magnetic field ($\mathsf{B}_{1}$ field) and cost far beyond 1 million €.}, author = {Chu, Anh and Kern, Michal and Khan, Khubaib and LiPS, Klaus and Anders, Jens}, booktitle = {2023 IEEE International Solid- State Circuits Conference (ISSCC)}, doi = {10.1109/ISSCC42615.2023.10067623}, issn = {2376-8606}, month = {02}, pages = {20-22}, title = {A 263GHz 32-Channel EPR-on-a-Chip Injection-Locked VCO-Array}, year = 2023 }

  @inproceedings{10186184, abstract = {Solid-state magnetometers based on color centers in diamond are emerging as one of the leading quantum sensors due to their outstanding room-temperature properties, such as high sensitivity and calibration-free long-term stability. However, their integration into compact systems is still an active area of research. To tackle this challenge, in this paper, we present a quantum magnetometer based on negatively charged nitrogen-vacancy (NV) centers using a custom-designed, chip-integrated 4-way transmitter. In combination with a custom-designed microcoil array, the 4-way transmitter delivers microwave magnetic fields up to 226 µT for carrier frequencies around 7 GHz with a conversion gain of ≥32 dB to NV centers. The local oscillator (LO) signal required to drive the on-chip quadrature upconversion mixer is generated by a custom-designed quadrature PLL, which provides a 22% tuning range between 6.4 and 8 GHz, and a low phase noise of -122 dBc/Hz at 1 MHz offset from a 7 GHz carrier, to enable broadband, low-noise magnetometry. To verify the excellent performance of the integrated electronics, we have embedded them into a widefield diamond magnetometer using off-chip scanning optics, achieving a state-of-the-art AC-magnetic field limit of detection of 300 pT/Hz1/2.}, author = {Lotfi, Hadi and Kern, Michal and Striegler, Nico and Unden, Thomas and Scharpf, Jochen and Schalberger, Patrick and Schwartz, Ilai and Neumann, Philipp and Anders, Jens}, booktitle = {2023 IEEE Radio Frequency Integrated Circuits Symposium (RFIC)}, doi = {10.1109/RFIC54547.2023.10186184}, issn = {2375-0995}, month = {06}, pages = {253-256}, title = {A Diamond Quantum Magnetometer Based on a Chip-Integrated 4-way Transmitter in 130-nm SiGe BiCMOS}, year = 2023 }

The modulator also features a newly proposed DC servo loop (DSL) that extends the modulator’s dynamic range in applications with a large DC bias current. This improvement breaks the intrinsic tradeoff between dynamic range and quantization noise floor of C-SDM for applications which require the digitization of AC currents in the presence of strong DC bias currents. Moreover, a resistive-steering DAC is proposed that allows for larger sampling frequencies than conventional resistive DACs while, at the same time, achieving lower noise floors compared to current-steering DACs. The proposed modulator architecture has been manufactured in 180 nm CMOS, and consumes 64 mW from a 3.3 V supply. The chip’s measured peak SNR and SNDR are 77 dB and 76.8 dB, respectively. The modulator can accommodate AC signal currents up to 137 µApp and features an integrated noise of 6.9 nArms over a 200 kHz bandwidth, corresponding to a noise floor of 15 pA/√Hz. An off-chip implementation of the proposed DSL verifies its positive effect on the modulator’s dynamic range (DR) without deteriorating the modulator’s noise performance and/or stability properties.}, author = {Mohamed, A. and Baumgärtner, L. and Zhao, J. and Djekic, D. and Anders, J.}, booktitle = {2022 IEEE International Symposium on Circuits and Systems (ISCAS)}, pages = {1-5}, title = {A current-mode Σ∆ modulator with FIR feedback and DC servo loop for an improved dynamic range}, year = 2022 }

The advances in high-precision analog front-end and data conversion circuits have opened up new opportunities in diverse application spaces. To keep fueling the evolution of emerging applications, such as health monitoring, industry 4.0, and internet of things, advanced sensing technology is required to further improve resolution, speed, as well as power and area efficiency of the system. This forum highlights the fundamental challenges with an emphasis on techniques to achieve the ultimate accuracy in analog circuits and data converters. Following an overview of analog-circuit challenges, a series of discussions start with essential high-accuracy voltage and frequency references along with the compensation techniques for their long-term drift, and then move on to the system-level functions of high-precision amplifiers, digital-to-analog converters, as well as overasampling and Nyquist-rate analog-to-digital converters, which are required to construct the overall signal chain.}, author = {Chae, Youngcheol and Shu, Yun-Shiang and Anders, Jens and Schaffer, Viola and Oshima, Takashi and Corsi, Marco}, booktitle = {2021 IEEE International Solid- State Circuits Conference (ISSCC)}, doi = {10.1109/ISSCC42613.2021.9365818}, issn = {2376-8606}, month = {02}, pages = {517-519}, title = {F2: Pushing the Frontiers in Accuracy for Data Converters and Analog Circuits}, volume = 64, year = 2021 }

This new family adds to the previously reported one, where the alcohol-amine ligand is triethanolamine (H3tea), and allows a one-to-one comparison between them. From a combined experimental study, that included DC and AC magnetometry as well as HF-EPR measurements, and a theoretical approach based on Broken-Symmetry DFT and CASSCF-SA-SOC ab-initio computations, we discuss the single molecule magnet (SMM) performance in these complexes. We focus in a few key structural parameters that correlate with the magnetization relaxation behaviour observed along the different explored lanthanide ions.}, author = {Funes, Alejandro V. and Perfetti, Mauro and Kern, Michal and Rußegger, Nadine and Carrella, Luca and Rentschler, Eva and van Slageren, Joris and Alborés, Pablo}, doi = {https://doi.org/10.1002/ejic.202100467}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/ejic.202100467}, journal = {European Journal of Inorganic Chemistry}, number = 31, pages = {3191-3210}, title = {Single Molecule Magnet Features in the Butterfly [CoIII2LnIII2] Pivalate Family with Alcohol-Amine Ligands}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1002/ejic.202100467}, volume = 2021, year = 2021 }

 @article{Leitao2021.05.13.444009, abstract = {Nanocharacterization plays a vital role in understanding the complex nanoscale organization of cells and organelles. Understanding cellular function requires high-resolution information about how the cellular structures evolve over time. A number of techniques exist to resolve static nanoscale structure of cells in great detail (super-resolution optical microscopy1, EM2, AFM3). However, time-resolved imaging techniques tend to either have lower resolution, are limited to small areas, or cause damage to the cells thereby preventing long-term time-lapse studies. Scanning probe microscopy methods such as atomic force microscopy (AFM) combine high-resolution imaging with the ability to image living cells in physiological conditions. The mechanical contact between the tip and the sample, however, deforms the cell surface, disturbs the native state, and prohibits long-term time-lapse imaging. Here, we develop a scanning ion conductance microscope (SICM) for high-speed and long-term nanoscale imaging. By utilizing recent advances in nanopositioning4, nanopore fabrication5, microelectronics6, and controls engineering7 we developed a microscopy method that can resolve spatiotemporally diverse three-dimenional processes on the cell membrane at sub-5nm axial resolution. We tracked dynamic changes in live cell morphology with nanometer details and temporal ranges of sub-second to days, imagining diverse processes ranging from endocytosis, micropinocytosis, and mitosis, to bacterial infection and cell differentiation in cancer cells. This technique enables a detailed look at membrane events and may offer insights into cell-cell interactions for infection, immunology, and cancer research.Competing Interest StatementThe authors have declared no competing interest.}, author = {Leitao, Samuel M. and Drake, Barney and Pinjusic, Katarina and Pierrat, Xavier and Navikas, Vytautas and Nievergelt, Adrian P. and Brillard, Charl{\`e}ne and Djekic, Denis and Radenovic, Aleksandra and Persat, Alex and Constam, Daniel B. and Anders, Jens and Fantner, Georg E.}, doi = {10.1101/2021.05.13.444009}, elocation-id = {2021.05.13.444009}, eprint = {https://www.biorxiv.org/content/early/2021/05/15/2021.05.13.444009.full.pdf}, journal = {bioRxiv}, publisher = {Cold Spring Harbor Laboratory}, title = {Time-resolved scanning ion conductance microscopy for three-dimensional tracking of nanoscale cell surface dynamics}, url = {https://www.biorxiv.org/content/early/2021/05/15/2021.05.13.444009}, year = 2021 }

Using our analysis, we show that flicker noise of the input differential pair can be a primary noise source under many practically relevant circumstances. Moreover, based on this extended analysis, we propose a complete design methodology for ultra-low-noise TIAs. To this end, we derive analytical noise equations that help to interpret and optimize the noise behavior of a TIA before performing detailed transistor-level simulations.

Resetting the FIR filter internal states in the incremental mode introduces initial transient overshoots, which can cause instability at high input amplitudes. To solve this problem, we propose the use of a purely resistive feedthrough path from the overall input to the second integrator input. This additional path alleviates the large transient swings associated with the incremental operation and extends the modulator's dynamic range (DR). Furthermore, we introduce a novel implementation of a fully differential dual return-to-zero (RTZ) resistive FIR DAC that eliminates inter-symbol interference (ISI) signal-dependent errors and, thereby, improves modulator linearity.

Calculations of the magnetoresistance using the Hikami–Larkin–Nagaoka model for two-dimensional transport allow us to extract the phase-coherence length for all samples as well as the spin–orbit length for the p-type doped samples. For pure Ge, we find phase-coherence lengths as long as (349.0 ± 1.4) nm and (614.0 ± 0.9) nm for n-type and p-type doped samples, respectively. The phase-coherence length decreases with increasing Sn concentration.

Conventional state-of-the-art NMR spectroscopy systems utilize bulky superconducting magnets, have a room-filling size, and cost millions of euros. Over the past decade, advances in permanent magnet technology have led to the availability of benchtop NMR spectrometers and even smaller NMR relaxometers for analyzing bulk material properties and performing immunoassays. With the availability of these smaller NMR magnets, NMR electronics have entered the focus of attention as a key component for miniaturized, portable NMR devices. Here, the on-chip NMR approach, in which all required electronics are realized on a single integrated circuit, allows for a realization in an ultra-small form factor and offers great promise for reducing the overall system cost. In this chapter, a comprehensive and self-contained overview of the on-chip NMR approach in the biomedical context will be given. After an introduction into the topic, the physical origin of the NMR signal will be discussed together with means of exciting and detecting it. This is followed by a review of conventional NMR electronics, including its key performance metrics. In the main part of this chapter, the NMR-on-a-chip approach is introduced, and its advantages and disadvantages are highlighted.

However, increasing the current amplifier bandwidth leads to increased current noise levels, which in turn obscures the current signal generated from stochastic collision electrochemistry experiments. The key to minimizing current noise is an experimental configuration that minimizes the input capacitance to the current amplifier. Here, we report a new strategy to minimize the input capacitance to a current amplifier by using a movable microscale electrochemical cell, formed at the end of a micropipette using a scanning electrochemical cell microscopy approach, to conduct electrochemical experiments in close proximity (∼300 μm) to a transimpedance amplifier.

The ability to deal with changing DC fields is crucial for a portable setup that is intended to be used in unshielded environments outside the lab.

The system consists of a custom-designed, CMOS-based active NMR field probe, a custom-designed, single-bit ΣΔ modulator and a commercial optical link. The low-IF architecture of the transceiver ASIC, reduces the required bandwidth in the digitizer to a few hundred kilohertz, enabling the use of a single-bit ΣΔ modulator, whose high frequency, one bit data stream is ideally suited for feeding the following optical link. The custom ΣΔ modulator uses a third order loop filter and employs a 12-tap FIR DAC to increase its robustness against clock jitter. It is manufactured in a 0.18 μm CMOS technology and achieves an SNDR of 72.19 dB over a Nyquist bandwidth of 800 kHz. In the proposed setup, the 1-bit output stream of the ΣΔ modulator directly feeds the driver of a commercial optical fiber link to transmit the NMR data from inside the NMR magnet to the remotely located digital signal processing unit with a very high robustness against EMI. In-situ NMR experiments with a 1.45 T benchtop magnet using a silicone sample demonstrate the very good performance of the overall system, achieving a frequency resolution of 12.6 Hz or 200 ppb in the estimation of the sample's NMR resonance frequency.

 @inproceedings{8702445, abstract = {In this paper, we present a new architecture for the receive-chain in clinical X-nuclei magnetic resonance imaging (MRI) experiments. The proposed architecture requires only a single tuning capacitor to tune the MRI receive coil to the Larmor frequency of the nucleus of interest. The tuning capacitor provides a noise-free preamplification of the MR signal, allowing for relaxed noise constraints in the design of the following high impedance low noise amplifier (LNA). Together with the new architecture, we present a custom designed CMOS LNA with a passband between 1.5 MHz and 90 MHz, covering all clinically relevant nuclei in a 1.5 T MRI system.

Herein, we report the synthesis of [U(TrenTIPS)(OCAs)] (2, TrenTIPS=N(CH2CH2NSiiPr3)3), which is the first isolable actinide-2-arsaethynolate linkage. UV-photolysis of 2 results in decarbonylation, but the putative [U(TrenTIPS)(As)] product was not isolated and instead only [{\{}U(TrenTIPS){\}}2($\mu$-$\eta$2:$\eta$2-As2H2)] (3) was formed. In contrast, reduction of 2 with [U(TrenTIPS)] gave the mixed-valence arsenido [{\{}U(TrenTIPS){\}}2($\mu$-As)] (4) in very low yield. Complex 4 is unstable which precluded full characterisation, but these photolytic and reductive reactions testify to the tendency of 2-arsaethynolate to fragment with CO release and As transfer. However, addition of 2 to an electride mixture of potassium-graphite and 2,2,2-cryptand gives [{\{}U(TrenTIPS){\}}2{\{}$\mu$-$\eta$2(OAs):$\eta$2(CAs)-OCAs{\}}][K(2,2,2-cryptand)] (5).

More specifically, it can be shown that increasing the number of FIR taps in I-ΣΔ feedback DACs could lead to instability or a reduced maximum stable amplitude (MSA), even when using a proper compensation path. However, by presetting the FIR feedback to a voltage close to the input signal, a larger number of FIR taps can be used, increasing the jitter robustness of the CT I-ΣΔ. This presetting is achieved using a low resolution Nyquist rate ADC to preset the FIR taps. Moreover, presetting the FIR feedback slightly increases the modulator's MSA and signal-to-noise ratio compared to a non-return-to-zero (NRZ) feedback. To validate the proposed presetting approach, a third-order I-ΣΔ-ADC employing a 12-tap FIR DAC with presetting using a 4-bit flash ADC is compared against a conventional NRZ DAC and a conventional FIR DAC without presetting in MATLAB/Simulink.}, author = {{Mohamed}, A. and {Sakr}, A. and {Anders}, J.}, booktitle = {2019 17th IEEE International New Circuits and Systems Conference (NEWCAS)}, doi = {10.1109/NEWCAS44328.2019.8961214}, month = {06}, pages = {1-4}, title = {FIR Feedback in Continuous- Time Incremental Sigma-Delta ADCs}, url = {https://ieeexplore.ieee.org/document/8961214/}, year = 2019 }

In addition, the proposed ASIC features a second VCO for an on-chip frequency downconversion via mixing. To allow for a precise derivation of the operating frequency from an external reference as it is required for quantitative ESR experiments, the two on-chip VCOs are embedded into an offset phase-locked loop.

The proposed architecture benefits from an intrinsically linear 1.5-bit ΣA DAC to resolve the fine bits of the SAR ADC after a coarse conversion phase with a monotonically switched capacitive DAC (CDAC). The achieved linearity relies neither on a highly matched CDAC nor on any dynamic linearization techniques but on a single calibration of the coarse CDAC using the available ΣA DAC at startup. Therefore, the CDAC can be sized solely upon noise requirements. The SAR ADC employs two parallel dynamic comparators for improved power efficiency.

 @article{8345577, abstract = {In this paper, a transimpedance amplifier (TIA) is presented that utilizes a modified pseudo-resistor (PR) with improved robustness against temperature and process variations, enhanced linearity, and reduced parasitics. Using a biasing scheme named pseudo current mirror, the conventional dependence on absolute process parameters is reduced to a dependence on matching of alike devices. The linearity and noise performance as well as the immunity against process variations of the presented TIA are improved by the series connection of multiple PR elements. Moreover, it is shown how implementing the design in a silicon-on-insulator (SOI) technology reduces critical parasitics, which in turn enables the use of the multi-element PR in highspeed, high-gain, and low-distortion TIAs. A prototype realization in a 180-nm CMOS SOI technology achieves a tunability in transimpedance of three orders of magnitude from 1 GΩ down to 1 MΩ with corresponding bandwidths from 8 kHz to 2 MHz. By design, the contribution of shot noise is rendered negligible and the white noise floor of the prototype realization approaches the theoretical thermal noise limit, e.g., 5.5 fA/√(Hz) for a transimpedance of 1 GΩ and 140 fA/√(Hz) for 1 MΩ. Total Hz for a harmonic distortion values of less than 0.1% are achieved for an input amplitude of 300 pAp-p for 1 GΩ, 4.0 nAp-p for 100 MΩ, and 40 nAp-p for 10 MΩ, and less than 1% is achieved for an input amplitude of 550 nAp-p for 1 MΩ. The presented TIA consumes an area of 0.07 mm2 and dissipates a power of 9.3 mW for the opamp and a maximum power of 0.2 mW for the PR from a 1.8-V supply.}, author = {{Djekic}, D. and {Fantner}, G. and {Lips}, K. and {Ortmanns}, M. and {Anders}, J.}, doi = {10.1109/JSSC.2018.2820701}, issn = {1558-173X}, journal = {IEEE Journal of Solid-State Circuits}, month = {07}, number = 7, pages = {1913-1923}, title = {A 0.1% THD, 1-M $\Omega$ to 1-G $\Omega$ Tunable, Temperature-Compensated Transimpedance Amplifier Using a Multi-Element Pseudo-Resistor}, url = {https://ieeexplore.ieee.org/document/8345577/}, volume = 53, year = 2018 }

That is, it includes all geometric and material properties of the coil and the phantom, the thermal noise as well as the target MR sequences. The proposed simulationdriven design flow is validated using a manufactured prototype coil, whose performance was optimized regarding its SNR performance, based on the presented design flow, by comparing the coil's measured performance against the simulated results. In these experiments, the mean and the standard deviation of the relative error between the simulated and measured coil sensitivity pattern were found to be μ = 1.79% and σ = 3.15%.

The broad scope of this approach is illustrated by the synthesis of a range of such complexes LnM: LnM(hfac)3(μ2-acac-O,O,O′)3 (Ln = La, Pr, Gd; M = Cr, Fe, Ga), with approximate three-fold symmetry.
