that exists between the p + InGaAs and the 2DEG in the channel exhibits low leakage and a high breakdown voltage. More importantly, the gate-to-channel separation is determined solely by MBE growth, which leads to high threshold uniformity. Any problems of gate contact resistance are addressed by ve

A complete empirical large-signal model for the GaAs-and GaN-based HEMTs is presented. Three generalized drain current I-V models characterized by the multi-bias Pulsed I-V measurements are presented along with their dependence on temperature and quiescent bias state. The new I-V equations dedicated
## Abstract In this paper, we have successfully developed an intellectual parameterโextraction methodology on the basis of a genetic algorithm (GA), involving the efficient searchโspace separation and localโminimaโconvergence prevention schemes. Via an evolutionary simulation tool complemented with
