This paper addresses a novel approach to account for trapping effects in the large-signal description of GaN HEMTs. Instead of relying on an internal effective gate voltage, which is not very intuitive, it is investigated how the Chalmers (Angelov) model parameters are altered by trapping. It is verified that such an approach enables reliable load-pull prediction over a wide range of drain bias voltages...
This paper presents a novel approach to account for trapping effects in GaN HEMT devices. Recent works demonstrated good results relying on physics-based model enhancements. Unfortunately, none of the models is yet part of standard HEMT models in commercial circuit simulators, and the effort in model parameter extraction is high. In this work, we were able to show that a comparable model accuracy...
GaN HEMT performance is still compromised by trapping effects, but no commercial circuit simulator already provides compact models that account for these effects. This work explores the capability of a standard Chalmers (Angelov) model to accurately predict the power amplifier operation of GaN HEMTs. It is shown that relying on pulsed S-parameters and by restricting the model to be valid only for...
