A nonlinear multi-bias model oriented to accurately predict the effects of charge-trapping in Gallium Nitride (GaN) HEMTs is proposed. As a case study, we considered a 0.25-μm 8×75-μm GaN HEMT. The model is identified by using CW low-frequency time-domain data and validated through high-frequency vector nonlinear measurements.

Abstract
A nonlinear multi-bias model oriented to accurately predict the effects of charge-trapping in Gallium Nitride (GaN) HEMTs is proposed. As a case study, we considered a 0.25-μm 8×75-μm GaN HEMT. The model is identified by using CW low-frequency time-domain data and validated through high-frequency vector nonlinear measurements.File in questo prodotto:
