180 Gbit/s 4:1 power multiplexer for NRZ‐OOK signals with high output voltage swing in SiGe BiCMOS technology

open access: yesElectronics Letters, Volume 56, Issue 2, Page 69-71, January 2020., 2020
A 4:1 multiplexer (MUX) circuit in SiGe BiCMOS technology intended to directly drive a plasmonic Mach–Zehnder modulator for transmitter applications is presented. To achieve the highest data rates at a high output voltage swing, a power MUX concept is applied that maps the high‐speed performance of the final clock signal onto the output data.

SI VIS vs SIS

open access: yes, 2022
Sis a été analysé par E. Dickey comme une particule enclitique focalisante, ayant perdu sa fonction de politesse. Nous revenons d'abord sur cette analyse ; nous reprenons ensuite la concurrence entre sīs et si uīs à la lumière principalement de Plaute.

First principles analysis on the stability of C, Sn atoms near the surface of Ge thin film

open access: yesNihon Kikai Gakkai ronbunshu, 2018
To apply the germanium (Ge) thin film for various electronic devices, energy band structure should be controlled by carbon (C) and/or Tin (Sn) doping. It is important to understand the stable atomic configurations of C and Sn atoms near the (001) surface

Polar response particles in French as remnants of ellipsis

open access: yesGlossa, 2020
Polar response particles have been at the center of lively debates in the recent and not so recent literature. One of these debates concerns the syntax of these particles, in particular whether they are pure sentential proforms or involve ellipsis.

Recent improvement of silicon absorption in opto-electric devices

open access: yesOpto-Electronic Advances, 2019
Silicon dominates the contemporary electronic industry. However, being an indirect band-gap material, it is a poor absorber of light, which decreases the efficiency of Si-based photodetectors and photovoltaic devices.
