Abstract
A method for operating a circuit includes providing a three terminal main transistor and a four terminal sense transistor having a field plate. The method includes simultaneously applying a gate pulse on a gate terminal of the sense transistor and a gate terminal of the main transistor, and applying a field plate pulse on a field plate of the sense transistor. The field plate pulse is synchronous and in phase with the gate pulse.
