Project: Model Extraction of GaN Transistors

Acronym: MEGaN
Main Objective:
The main objective of MEGaN is exactly to propose and extract a nonlinear electro-thermal model of GaN HEMTs encapsulated and in die form. For that, first a complete small signal equivalent circuit extraction set-up will be created, which will be then complemented by a nonlinear pulsed I/V (Ids(Vgs,Vds)), Q/V (Cgs(Vgs) and Cgd(Vgd)) and thermal characterization. The electro-thermal model thus proposed will be validated for output power, power added efficiency and linearity, by the design and test of a microwave power amplifier prototype. So, a final objective of MEGaN is also to present a preview of the expected capabilities of those devices for RF applications.
