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…

Investigation of the origin of deep levels in Carbon-doped AlN/GaN/AlGaN HEMTs

L. Ben Hammou, Francois Grandpierron, Elodie Carneiro, Katir Ziouche, Etienne Okada, F Medjdoub

<div><p>In this work, we focused on understanding the origin and impact of deep levels in various AlN/GaN HEMTs with carbon doped GaN buffer including or not an AlGaN back barrier. It is shown that the inclusion of a back barrier reduces drastically the current collapse. Furthermore, we…

Implementation of High-Speed Multi-Trit Adders for Balanced and Unbalanced Ternary Logic

Guangchao Zhao, Zhiwei Zeng, Huamin Jie, Xingli Wang, Philippe Coquet, Mingqiang Huang, Beng Kang Tay

Ternary logic with larger data density has great potential in high-performance data processing. Even though ternary half/full adders have been intensively investigated in recent years, the high-speed multi-trit ternary adders, which are urgently needed for high-efficient ternary computing, remain…
