About 250/285 GHz push–push oscillator using differential gate equalisation in digital 65‐nm CMOS

Bassem Fahs, Kefei Wu, Walid Aouimeur, Muhammad Waleed Mansha, Christophe Gaquière, Patrice Gamand, Wojciech Knap, Mona M. Hella

This study presents a push-push oscillator architecture based on differential gate equalisation to enhance theoscillation frequency while providing relatively high output power with ultra-compact layout form factor. The frequencyenhancement is derived as a function of the equivalent RLC model of...

Passive guided wave tomography for structural health monitoring

Tom Druet, Arnaud Recoquillay, Bastien Chapuis, Emmanuel Moulin

In this paper is presented a baseline-free quantitative method for imaging corrosion flaws in thin plates. It only requires an embedded guided wave sensor network used in a fully passive way, i.e. without active emission of waves. This method is called passive guided waves to-mography. The aim of...

High Lateral Breakdown Voltage in Thin Channel AlGaN/GaN High Electron Mobility Transistors on AlN/Sapphire Templates

Idriss Abid, Riad Kabouche, Catherine Bougerol, Julien Pernot, Cédric Masante, Rémi Comyn, Yvon Cordier, F Medjdoub

In this paper, we present the fabrication and Direct Current/high voltage characterizations of AlN-based thin and thick channel AlGaN/GaN heterostructures that are regrown by molecular beam epitaxy on AlN/sapphire. A very high lateral breakdown voltage above 10 kV was observed on the thin channel...

Thermal conductivity and transport modes in glassy GeTe 4 by first-principles molecular dynamics

Thuy-Quynh Duong, Carlo Massobrio, Guido Ori, Mauro Boero, Évelyne Martin

First principles molecular dynamics is employed to investigate thermal transport in glassy GeTe4, a subsystem of several ternary phase-change materials. As a first result, we found modes localized on a few atoms in the vibrational density of states. The thermal transport is further rationalized by...

3D FEM analysis of high-frequency AlN-based PMUT arrays on cavity SOI

Wen-Juan Liu, Leming He, Xubo Wang, Jia Zhou, Wei-Jiang Xu, Nikolay Smagin, Malika Toubal, Hao Yu, Yuandong Gu, Jinghui Xu, Denis Remiens, Junyan Ren

This paper presents three-dimensional (3D) models of high-frequency piezoelectric micromachined ultrasonic transducers (PMUTs) based on the finite element method (FEM). These models are verified with fabricated aluminum nitride (AlN)-based PMUT arrays. The 3D numerical model consists of a...

[Invited] Optimization of quasi-periodically ribbed structures to improve stealth and discreteness of underwater vehicles

Bertrand Dubus, Charles Croënne, Samuel Deleplanque, Anne-Christine Hladky

Acoustic stealth and discreteness of underwater vehicles are important issues in underwater acoustics. These vehicles are constituted of shells which are periodically reinforced by ribs. Acoustic fields radiated or scattered by such structures are strongly affected by phenomena related to this...
