  @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 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 }

 @inproceedings{9567831, abstract = {In this paper, we present a widely tunable transimpedance amplifier (TIA) with a dc servo loop and an optional bandwidth extension. All resistors are implemented as multielement pseudo-resistors, which feature high linearity, robustness against process and temperature variations, and a very wide tuning range of more than five decades. While state-of-the-art TIAs are mainly implemented with either resistive or capacitive feedback, the proposed TIA uses a capacitive-resistive feedback network to combine the best of both topologies. The TIA features a noise floor of 0.6 fA/✓Hz at its maximum transimpedance of 150 GΩ and a bandwidth of 2.9 MHz at its minimum transimpedance of 440 kΩ. A subsequent inverting amplifier stage provides an optional pole-zero compensation to extend the TIA's overall bandwidth by a factor of up to 180 or with an absolute limit of 2.3 MHz. An additional dc servo loop, which incorporates a tunable integrator and a tunable dc feedback resistor, can be used to prevent large dc currents from flowing through the main signal path. Its dc transimpedance can be adjusted separately from the ac transimpedance, and the crossover frequency is adjustable over a range of more than five decades. The TIA occupies 0.3 mm2 of chip area and has a power consumption of 40 mW from a 1.8-V supply.}, author = {Djekic, Denis and Häberle, Matthias and Mohamed, Ayman and Baumgärtner, Lars and Anders, Jens}, booktitle = {ESSCIRC 2021 - IEEE 47th European Solid State Circuits Conference (ESSCIRC)}, doi = {10.1109/ESSCIRC53450.2021.9567831}, month = {09}, pages = {403-406}, title = {A 440-kOhm to 150-GOhm Tunable Transimpedance Amplifier based on Multi-Element Pseudo-Resistors}, year = 2021 }

In this letter, a 12-to-15b resolution reconfigurable power scalable Nyquist-rate incremental ΔΣ (I-ΔΣ) ADC, operating at sampling rates from 100 to 25 kS/s, is proposed. A widely reconfigurable dynamic range (DR) (73-92 dB) with fine selection granularity is achieved by incorporating a scalable first integrator and optimally setting the oversampling ratio (OSR) of the ΔΣ modulator. A 2.5× power reduction is measured for the proposed technique in comparison to a pure OSR-based resolution scaling. A Walden figure-of-merit (FoM W) of 880 fJ/conv.-step and Schreier (FoM S) of 160.3 dB are measured in the 14b mode. The I-ΔΣ ADC is fabricated in a 180-nm CMOS technology and consumes 0.48 and 0.93 mW from a supply voltage of 3 V at the 12b and 15b modes, respectively.

 @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 }

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. The presented design is fabricated in a 180-nm SOI CMOS technology and achieves a DR of 90.3 dB and a peak spurious-free DR of 93.1 dB at a Nyquist conversion rate of 1 MS/s.

 @inbook{Anders2020, abstract = {Nuclear magnetic resonance (NMR) is one of the prime modalities for probing molecular structure in the biomedical context and analyzing bulk material properties for quality control, food product analysis, and nondestructive testing. 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. Finally, the chapter is concluded with a summary and an outlook on the possibility of enhancing the achievable performance of the NMR-on-a-chip approach with on-chip dynamic nuclear polarization (DNP) capabilities.}, address = {New York, NY}, author = {Anders, Jens and Dreyer, Frederik and Kr{\"u}ger, Daniel}, booktitle = {Handbook of Biochips: Integrated Circuits and Systems for Biology and Medicine}, doi = {10.1007/978-1-4614-6623-9_23-1}, editor = {Sawan, Mohamad}, isbn = {978-1-4614-6623-9}, pages = {1--32}, publisher = {Springer New York}, title = {On-Chip Nuclear Magnetic Resonance}, url = {https://doi.org/10.1007/978-1-4614-6623-9_23-1}, year = 2020 }

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.
