Abstract

Here, we present the modeling of temperature effects in the surface potential based 'Advanced Spice Model for High Electron Mobility Transistor' (ASM-HEMT) for AlGaN/GaN HEMTs. We extract the temperature dependencies of mobility, saturation velocity, cut-off voltage and access resistance parameters of this model. This enables accurate modeling of I-V, g_m and g_ds at multiple temperatures. Our model is compared with measured data and shows excellent fitting for a wide range of temperature.
