ABSTRACT:
A composite field effect transistor, in accordance with one embodiment, includes a zener diode, a junction field effect transistor and a metal-oxide-semiconductor field effect transistor. A gate of the junction field effect transistor is coupled to an anode of the zener diode. A cathode of the zener diode is coupled to a gate of the metal-oxide-semiconductor field effect transistor. A drain of the metal-oxide-semiconductor field effect transistor is coupled to a source of the junction field effect transistor.
