Abstract :
Device models to support circuit design efforts using monolithically-integrated enhancement- and depletion-mode high-speed InAlN/AlN/GaN HEMTs are reported. Physically- motivated modifications to the conventional empirical compact models have been included to enhance model accuracy over bias and temperature. The models have been extracted from DC through 110 GHz at baseplate temperatures from 25 °C through 100 °C; good agreement is obtained between measurement results and the extracted model.
