Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
Distributed compressed sensing is the extension of compressed sampling (CS) to sensor networks. The idea is to design a CS joint decoding scheme at a central decoder (base station) that exploits the inter-sensor correlations, in order to recover the whole ...
In this paper, we study the operation of MOS current-mode logic (MCML) gates at lower-than-nominal supply voltages.We show that power can be traded for speed by reducing the supply voltage below the nominal value, while the power-delay product stays nearly ...
This paper presents the design, realization and characterization of a new hybrid A/D converter based on a combined incremental and cyclic conversion. The proposed implementation offers a configurable resolution, and permits to share the same hardware for t ...
A model is proposed to describe the fundamental read range limitation due to the local oscillator phase noise in the reader, in IF-based, far-field RFID systems using amplitude-shift keying backscatter modulation. The relation between the system parameters ...

This article presents a power-efficient low-voltage differential signaling (LVDS) output driver circuit. The proposed approach helps to reduce the total input capacitance of the LVDS driver circuit and hence relaxes the tradeoffs in designing a low-power p ...
This article explores the effect of using source follower buffers (SFB) at the output of source coupled logic (SCL) circuits. This technique can help to improve the power-delay product (PDP) in an SCL gate by a factor close to two. The proposed approach ha ...
This paper presents a new two-sections architecture of a low power switched capacitor (SC) finite impulse response (FIR) filter suitable for base-band signal processing in WCDMA and in GSM standards. The low power operation is possible due to several optim ...
We consider a cognitive radio network in which a base station provides opportunistic unlicensed spectrum access for secondary base stations to transmit data to their subscribers. The primary user may decide to release some parts of its bandwidth for the us ...
In bioelectric recordings, an electrode-skin impedance mismatch leads to a reduced common-mode rejection ratio (CMRR) of the amplifier. For this reason, the impedance of each individual electrode-skin contact is usually measured prior to a recording. The m ...
In this paper we present Matlab analysis as well as CMOS implementation of an analog current mode Kohonen neural network (KNN). The presented KNN has been realized using several building blocks proposed earlier by the authors, such as: binary tree winner t ...
