A Unified Explanation of gm /ID -Based Noise Analysis

Jack Ou, Pietro Maris Ferreira

We present an unified explanation of the transconductance-to-drain current (gm/ID)-based noise analysis in this paper. We show that both thermal noise coefficient (γ) and device noise corner frequency (fco) are dependent on the gm/ID of a transistor. We derive expressions to demonstrate the...

Time-Frequency Processing Adapted for the Different Electromagnetic Compatibility Issues in the Railway Domain

Mohammed Raouf Kousri, Virginie Deniau, Marc Heddebaut, S. Baranowski, Jean Rioult

The railway environment is very rich in terms of electromagnetic disturbances. The variety of the transient and permanent interferences and the current evolution of the communication and signaling railway systems require the adaptation of EMC railway standards. In particular, standardized emission..., L'environnement électromagnétique du chemin de fer est très riche en termes de perturbations électromagnétiques. La variété des signaux transitoires et des interférences permanentes et l'évolution actuelle des systèmes de communication et de signalisation ferroviaire nécessitent l'...

Drift velocity versus electric field in < 110 > Si nanowires: Strong confinement effects

Jing Li, Gabriel Mugny, Yann-Michel Niquet, Christophe Delerue

We have performed atomistic simulations of the phonon-limited high field carrier transport in < 110 > Si nanowires with small diameter. The carrier drift velocities are obtained from a direct solution of the non-linear Boltzmann transport equation. The relationship between the drift velocity...

The beginnings of plasmomechanics : towards plasmonic strain sensors

Thomas Maurer, Joseph Marae Djouda, Ugo Cataldi, Arthur Gontier, Guillaume Montay, Yazid Madi, Benoît Panicaud, Demetrio Macías, Pierre-Michel Adam, Gaëtan Lévêque, Thomas Bürgi, Roberto Caputo

This article exposes the beginnings of a new field which could be named as “plasmomechanics”. Plasmomechanics comes from the convergence between mechanics and plasmonics. Here we discuss a relatively recent topic whose technological aim is the development of plasmonic strain sensors. The idea is...
