Abstract :
Switching GaN-based devices from a quiescent drain bias point in pinch-off to an open channel condition such as in pulsed power operation will cause thermal transients due to self-heating and electronic transients owing to charge storage effects with opposite gradients. The superposition of both effects may result in a complex transient behaviour or even cancellation
