Abstract

A circuit includes a transistor having a source, drain, a gate, and an electrode structure. A source terminal is coupled to the source. A drain terminal coupled to the drain. Terminals are coupled to the gate and to the electrode structure. A switch is coupled to the source, the gate terminal and the electrode terminal to selectively couple one of the gate and electrode structure to the source. In further embodiments, a second switch is used to selectively couple a resistor between the gate and the source. A method is used to control the switches to keep the transistor in an off state or allow it to switch to an on state.
