Graphene quantum capacitors for high-Q tunable LC-tanks for RF ICs
Juan Ramon Mosig, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Michele Tamagnone, Wolfgang Amadeus Vitale
We propose and characterize graphene quantum capacitors, tunable with voltage by the control of their charge density, for tunable LC tanks as essential building blocks for Radio-Frequency (RF) functions in densely integrated circuits. We fabricate and inve ...
IEEE2016Solutions for thermally mismatched brazing operations for ceramic tokamak magnetic sensor
Duccio Testa, Peter Ryser, Matthieu Toussaint, Thomas Maeder, Caroline Jacq, Philipp Windischhofer, Xinyue Jiang
To monitor high-frequency fluctuations of the equilibrium magnetic field in tokamaks, a 3D magnetic sensor has been developed. The sensor, which is positioned inside the vacuum vessel behind the protective tiles of the tokamak and is exposed to potential t ...
2016Thermal gate, a new tool for ionic transport control inside nanochannels
Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor
Transport of ionic species solvated in electrolytes depends on temperature. This dependence is much stronger in nanofluidics than large scale since the surface charge also varies with temperature. In this work, we introduce a new tool for the modulation of ...
IEEE2015An improved trap design for decoupling multinuclear RF coils
Rolf Gruetter, Eulalia Serés Roig
Purpose Multinuclear magnetic resonance spectroscopy and imaging require a radiofrequency probe capable of transmitting and receiving at the proton and non-proton frequencies. To minimize coupling between probe elements tuned to different frequencies, LC ( ...
Wiley-Blackwell2014Accurate Capacitor Voltage Ripple Estimation and Current Control Considerations for Grid-Connected Modular Multilevel Converters
Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix
In this paper the analytical solution for the submodule voltage ripple equations of a Modular Multilevel Converter (MMC) is derived, based on the knowledge of the external voltage/current magnitudes, and enhancing a concept previously presented in literatu ...
Ieee-Inst Electrical Electronics Engineers Inc2014Lithography: Hybrid Helical Magnetic Microrobots Obtained by 3D Template-Assisted Electrodeposition (Small 7/2014)
Mahmut Selman Sakar, Berna Ayse Özkale Edelmann
Hybrid artificial flagella (h-ABF) consisting of a ferromagnetic alloy head and a helical polymer tail can be fabricated by sequential electrodeposition of a cobalt-nickel alloy and polypyrrole inside a photoresist template patterned by 3D laser lithograph ...
Wiley-Blackwell2014A 3.1 mW 8b 1.2 GS/s Single-Channel Asynchronous SAR ADC With Alternate Comparators for Enhanced Speed in 32 nm Digital SOI CMOS
Yusuf Leblebici, Lukas Kull, Thomas Toifl
An 8b 1.2 GS/s single-channel Successive Approximation Register (SAR) ADC is implemented in 32 nm CMOS, achieving 39.3 dB SNDR and a Figure-of-Merit (FoM) of 34 fJ per conversion step. High-speed operation is achieved by converting each sample with two alt ...
Institute of Electrical and Electronics Engineers2013A 35mW 8 b 8.8 GS/s SAR ADC with Low-Power Capacitive Reference Buffers in 32nm Digital SOI CMOS
Yusuf Leblebici, Lukas Kull, Thomas Toifl
An asynchronous 8x interleaved redundant SAR ADC achieving 8.8GS/s at 35mW and 1V supply is presented. The ADC features pass-gate clocking for time-skew minimization and per-channel gain control based on low-power reference voltage buffers. The sub-ADC sta ...
2013Polymer-based flexible capacitive sensor for three-axial force measurements
Martinus Gijs, Jagoda Anna Dobrzynska
We have developed a flexible-substrate-based three-axial force sensor, composed of finger-shaped electrode capacitors, whose operation is based on the measurement of a capacitance change induced upon applying a three-axial load. The electrode design suppor ...
Institute of Physics2013Système de conversion d'énergie
Yves Perriard, Paolo Germano, Christophe Bruno Auvigne
The system (20) has a switching unit (T1) adapted for switching reversibly between two configurations. A capacitor is connected in series between a secondary winding (9) and a connection terminal (A) in one of the configurations. Another capacitor is conne ...
