Semiconductor device and circuit with dynamic control of electric field

摘要

A circuit, comprising a semiconductor device with one or more field gate terminals for controlling the electric field in a drift region of the semiconductor device; and a feedback circuit configured to dynamically control a bias voltage or voltages applied to the field gate terminal or terminals, with different control voltages used for different semiconductor device characteristics in real-time in response to a time-varying signal at a further node in the circuit.
