Three-wave-mixing quantum-limited kinetic inductance parametric amplifier operating at 6 T near 1 K
Pasquale Scarlino, Simone Frasca, Guillaume Beaulieu, Camille René Charles Roy
Parametric amplifiers play a crucial role in modern quantum technology by enabling the enhancement of weak signals with minimal added noise. Traditionally, Josephson junctions have been the primary choice for constructing parametric amplifiers. Nevertheles ...
2024High current power amplifier board design for SMA-based actuator fast heating
The main objective of this project is to implement a power amplifier that can be used to drive a shapememory alloy (SMA) currently being developed by Ms. Marjan Ghorbani. The secondary objective is to make the device versatile enough such that other resear ...
2023Amorphous Silicon Based Microchannel Plates for Time-of-Flight Positron Emission Tomography
Microchannel plates fabricated from hydrogenated amorphous silicon (AMCPs) are a promising alternative to conventional lead glass microchannel plates. Their main advantages lie in their cheaper and more flexible fabrication processes, allowing for adaptabl ...
EPFL2023A Cryo-CMOS Wideband Quadrature Receiver With Frequency Synthesizer for Scalable Multiplexed Readout of Silicon Spin Qubits
Edoardo Charbon, Andrea Ruffino, Yatao Peng
In this article, a cryo-CMOS receiver integrated with a frequency synthesizer for scalable multiplexed readout of qubits is presented, focusing on radio frequency (RF) reflectometry readout of silicon-based semiconductor spin qubits/quantum dots. The propo ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022A Delta Sigma-Modulated Sample and Average Common-Mode Feedback Technique for Capacitively Coupled Amplifiers in a 192-nW Acoustic Analog Front-End
This work presents an acoustic analog front-end based on a delta sigma-modulated sample and average common-mode feedback technique. The proposed feedback offers a process and temperature stable high pass (HP) frequency corner, unity dc feedback gain, and a ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Measurements and analysis of different front-end configurations for monolithic SiGe BiCMOS pixel detectors for HEP applications
This paper presents a small-area monolithic pixel detector ASIC designed in 130 nm SiGe BiCMOS technology for the upgrade of the pre-shower detector of the FASER experiment at CERN. The purpose of this prototype is to study the integration of fast front-en ...
IOP Publishing Ltd2021Performance of chip-scale optical frequency comb generators in coherent WDM communications
Optical frequency combs have the potential to become key building blocks of wavelength-division multiplexing (WDM) communication systems. The strictly equidistant narrow-band spectral lines of a frequency comb can serve either as carriers for parallel WDM ...
OPTICAL SOC AMER2020On the effect of linear feedback and parametric pumping on a resonator's frequency stability
Luis Guillermo Villanueva Torrijo
Resonant sensors based on micro- and nano-electro mechanical systems (M/NEMS) are ubiquitous in many sensing applications due to their outstanding performance capabilities, which are directly proportional to the quality factor (Q) of the devices. We addres ...
2020Fully symmetrical single-suspension electrodynamic loudspeaker using a Halbach array
Invented at the end of the XIXth century, the electrodynamic loudspeaker has not much changed sincethen. Although the materials have greatly evolved, the geometry and the transduction principle staythe same. In many applications, the presence of two sets o ...
Canadian Acoustical Association2019Langmuir probe electronics upgrade on the tokamak a configuration variable
Benoît Labit, Christian Gabriel Theiler, René Chavan, Pierre Lavanchy, Richard Pitts, Philippe Marmillod, Blaise Marlétaz, Hugo De Oliveira
A detailed description of the Langmuir probe electronics upgrade for TCV (Tokamak a Configuration Variable) is presented. The number of amplifiers and corresponding electronics has been increased from 48 to 120 in order to simultaneously connect all of the ...
