Design of Power Amplifiers

The activity started when I joined the ECIME team and continued in the ETIS laboratory. The goal is to find design methods or architectures to address the tradeoffs between high efficiency and linearity in power amplifiers.
Currently, a thesis on the linearity / efficiency tradeoff with the ACCO industrial is in progress with a silicium high efficiency power amplifier already realized.

Failure mechanism analysis in AlGaN/GaN power HEMTs

This research theme deals with the failure analysis of power hemts, currently AlGaN/GaN hemts. The study is based on the design of test amplifiers, their characterization and their stress on ageing benches. The objective is to propose a methodology aimed toward discriminating predominant degradation modes and to suggest a link between the evolution of electrical performances and physical roots of these defects.
