A new, simplified empirical large-signal model for high power microwave SiC MESFETs is presented. A generalized drain current source equation is developed, allowing close predictions of both pulsed and static IV characteristics, which vary significan
A complete empirical large-signal model for high-power AlGaN/GaN HEMTs (GaN HEMT) utilizing an improved drain current (Ids ) formulation with self-heating and charge-trapping modifications is presented. The new drain current equation accurately model
