Electromagnetic only HEMT model for switch design

Electromagnetic (EM) only HEMT model has been proposed and realized with commercial available EM simulator. EM analysis has been applied, for the first time, to the intrinsic part of HEMT device. The small signal behaviors of HEMT can be accurately predicted based directly on the layout and process information. After introducing two EM HEMT models for HEMTs in both on and off states, entire switch circuit, as a whole, can be EM simulated. The prediction accuracy for switch performance can be remarkably improved by taking into account all of the distributed and coupling effects inside the circuit.
