The increased usage of high electron mobility transistors (HEMTs), especially using GaN, for a large range of applications demands for efficient circuit design models. The paper discusses the procedures for determining key parameters of a physics-based HEMT model for circuit design. HEMTs using AlGaN/GaN epitaxy on Si substrate fabricated at IESL-FORTH are used. Basic parameters such as barrier capacitance, threshold voltage, slope factor, and mobility are determined from experimental characteristics over a large range of temperature. It is shown that the behavior of HEMTs, in terms of transconductance efficiency, is in many ways similar to that of MOSFETs.
