Abstract

In this paper, we have used electrical specifications from the data-sheet of a commercially available GaN HEMT power device and a well calibrated physical model using ASM-GaN [1], [2] compact model as a starting point to arrive at corner and statistical models of that device using Backward Propagation of Variance (BPV). Both dc (Vth, RDS(on)) and ac (Ciss, Coss, Crss Rg) electrical specifications were used to derive the models. Furthermore, the statistical model was used to perform Monte Carlo simulations for the gate charge and switching transients in order to determine the distribution of circuit level electrical specifications from the underlying variations in the statistical model.
