Abstract:

On-state gate leakage current behavior of AlGaN/GaN high electron mobility transistors (HEMTs) has been studied by using Technology Computer Aided Design (TCAD) simulation. We found the gate leakage current increases above the pinch-off voltage, which is different from the case of a two-terminal operation. This gate leakage current increase is due to self-heating effect at the gate edge of the drain side where the gate leakage occurs.
