AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Design and optimization of a simple but efficient operational amplifier (OA) for switched-capacitor finite impulse response (SC FIR) filters are presented. The main design criteria are: proper characteristics for application in SC FIR filters, simplicity o ...
Time of flight (TOF) measurements in positron emission tomography (PET) are very challenging in terms of timing performance, and should achieve ideally less than 100ps FWHM precision. We present a time-based differential technique to read out SiPMs that ha ...
This article explores the main tradeoffs in design of power and area efficient bandgap voltage reference (BGR) circuits. A structural design methodology for optimizing the silicon area and power dissipation of CMOS BGRs will be introduced. For this purpose ...
The authors describe techniques to make fast, sub-nanosecond time resolution solid-state detector systems using sensors with 3D electrodes, current amplifiers, constant-fraction comparators or fast wave-form recorders, and some of the next steps to reach s ...
A set of novel silicate glasses containing ZnO and co-doped with Er3+ and Yb3+ was designed as substrates for optical waveguide amplifiers. Characterized by exceptionally low up-conversion, minimum Er concentration quenching and high mechanical as well as ...

An event-driven analogue-to-digital converter (ADC) architecture is proposed. The proposed architecture has less sensitivity to amplifier and DAC nonlinearity, and reduces the swing and dynamic common-mode range requirement of the operational transconducta ...
We present a concept of "active material" with variable acoustic properties, being constituted of an electroacoustic transducer which acoustic impedance can be changed by an active mean. Among the different ways to obtain variable acoustic properties on an ...
In this paper, the liner concept is an electroacoustic transducer which acoustic impedance can be changed by electrical means, be it passive or active. Among the different ways to obtain variable acoustic properties on an electroacoustic transducer's voici ...
This research work deals with the design of linear CMOS RF power amplifiers. Two important aspects are treated: efficiency enhancement and frequency-tunable capability. For this purpose, two different integrated circuits were realized in a 0.11 µm technolo ...
An innovative readout channel, based on analog amplitude modulation (AM) of the signals recorded by each electrode, is developed for high-density CMOS-based MEAs. This new readout method enables the design of a low-noise amplification stage while still rea ...
