Abstract :
In this paper, we describe a pulsed characterization of a 0.25-μm GaN FET (W = 1 mm) at different operating temperatures. Through the use of a pulsing set-up featuring a VNA-like architecture, the drain DC current component is monitored and the effects of the AC-to-DC conversion due to nonlinear charge trapping phenomena are evaluated under various thermal conditions.
