A Low-Power 9-Bit 222 MS/s Asynchronous SAR ADC in 65 nm CMOS
Yusuf Leblebici, Firat Çelik, Ayça Akkaya
This paper presents a 9-bit 222 MS/s low-power asynchronous single-bit/cycle successive approximation register (SAR) ADC. The SAR ADC combines techniques such as asynchronous clocking, binary-weighted custom-designed capacitive DAC with small unit capacito ...
IEEE2020White-line evolution in shocked solid Ta evidenced by synchrotron x-ray absorption spectroscopy
Time-resolved x-ray absorption experiments have been performed on shocked tantalum. Using a single 100 ps synchrotron x-ray pulse, nanosecond-lived equilibrium states of shocked solid Ta have been measured by L-3-edge absorption spectroscopy. The energy sh ...
2020An AC-Coupled Wideband Neural Recording Front-End With Sub-1 mm2×fJ/conv-step Efficiency and 0.97 NEF
Volkan Cevher, Arda Uran, Yusuf Leblebici
This letter presents an energy-and-area-efficient ac-coupled front-end for the multichannel recording of wideband neural signals. The proposed unit conditions local held and action potentials using an inverter-based capacitively coupled low-noise amplifier ...
2020Band Filling and Cross Quantum Capacitance in Ion-Gated Semiconducting Transition Metal Dichalcogenide Monolayers
Helmuth Berger, Thierry Giamarchi, Christophe Berthod, Haijing Zhang
Ionic liquid gated field-effect transistors (FETs) based on semiconducting transition metal dichalcogenides (TMDs) are used to study a rich variety of extremely interesting physical phenomena, but important aspects of how charge carriers are accumulated in ...
2019Origin of apparent light-enhanced and negative capacitance in perovskite solar cells
Wolfgang Richard Tress, Ulf Anders Hagfeldt, Firouzeh Ebadi Garjan
So-called negative capacitance seems to remain an obscure feature in the analysis of the frequency-dependent impedance of perovskite solar cells. It belongs to one of the puzzling peculiarities arising from the mixed ionic-electronic conductivity of this c ...
Springer2019Color neutral nanocomposite nickel-tantalum oxide for electrochromic windows
Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard
Electrochromic windows can darken on demand to limit the solar gains entering a building to reduce the risk of overheating, while preserving the view towards the exterior. Yet, the switching speed and contrast as well as the durability of commercial produc ...
IOP2019Full Discrete Modeling, Controller Design, and Sensitivity Analysis for High-Performance Grid-Forming Converters in Islanded Microgrids
Francisco Daniel Freijedo Fernández, Federico De Bosio
Recent works have shown that the state-feedback decoupling of capacitor voltage allows for drastic bandwidth enlarging of current controllers for grid-forming converters in islanded microgrids. Furthermore, Smith predictor and lead compensation have been a ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2018Discrete-Time Domain Modeling of Voltage Source Inverters in Standalone Applications: Enhancement of Regulators Performance by Means of Smith Predictor
Francisco Daniel Freijedo Fernández, Federico De Bosio
The decoupling of the capacitor voltage and inductor current has been shown to improve significantly the dynamic performance of voltage source inverters in standalone applications. However, the computation and pulse width modulation delays still limit the ...
Ieee-Inst Electrical Electronics Engineers Inc2017Electronics Emulation for Real-Time Fault Location in Power Systems
This research presents a high-speed hardware platform dedicated to emulate electrical power networks for the fault location. The solution implements an algorithm based on the Electromagnetic Time-Reversal (EMTR) principle, which allows locating faults in v ...
EPFL2017A transparent silk-fibroin-based triboelectric microgenerator for airflow energy harvesting
Jürgen Brugger, Xiao Sheng Zhang, Ya Wang, Yinben Guo
We present a new transparent high-performance triboelectric microgenerator (TEMG) based on an emerging material, silk fibroin. Silk fibroin has a strong ability to lose electrons and occupies a top-level positive position in the triboelectric series. It th ...
