Toward Accurate Analysis of Channel Charge Injection in SAR ADCs' Capacitive DACs

Alireza Ahrar, Jianxiong Xu, Mohammad Reza Pazhouhandeh, Antoine Frappé, Mostafa Rahimi Azghadi, Amirali Amirsoleimani

This paper conducts a detailed analysis of the impact of channel charge injection on the capacitive digital-to-analog (DAC) block in successive-approximation register (SAR) analog-to-digital converters (ADCs). It introduces a CAD tool for distinguishing various non-idealities, quantifying channel…

Impact of Carbon-doped AlGaN back barrier in AlN/GaN/AlGaN HEMTs

François Grandpierron, Elodie Carneiro, L. Ben Hammou, Etienne Okada, J. Strate, M. Germain, F Medjdoub

<div><p>The impact of carbon doping into the AlGaN back barrier in AlN/GaN HEMTs is investigated. In this work, we demonstrate that a back polarization itself is not enough to ensure a proper electron confinement under high field, especially when using sub-150 nm. Experimental results…

[Best paper award] GLIP: Electromagnetic Field Exposure Map Completion by Deep Generative Networks

Mohammed Mallik, Davy Gaillot, Laurent Clavier

<div><p>In Spectrum cartography (SC), the generation of exposure maps for radio frequency electromagnetic fields (RF-EMF) spans dimensions of frequency, space, and time, which relies on a sparse collection of sensor data, posing a challenging ill-posed inverse problem. Cartography…
