Abstract: Modeling the temperature-dependent nonlinearity of intrinsic capacitances in AlGaN/GaN high electron mobility transistors (HEMTs) improves model accuracy. In this letter, extraction results indicate that the current modeling methods cannot accurately reflect the variations of nonlinearity… read more here.
