MONOLITHIC CHARGE COUPLED FIELD EFFECT RECTIFIER EMBEDDED IN A CHARGE COUPLED FIELD EFFECT TRANSISTOR

摘要

An integrated circuit includes a MOSFET device and a monolithic diode device, wherein the monolithic diode device is electrically connected in parallel with a body diode of the MOSFET device. The monolithic diode device is configured so that a forward voltage drop VfD2 of the monolithic diode device is less than a forward voltage drop VfD1 of the body diode of the MOSFET device. The forward voltage drop VfD2 is process tunable by controlling a gate oxide thickness, a channel length and body doping concentration level. The tunability of the forward voltage drop VfD2 advantageously permits design of the integrated circuit to suit a wide range of applications according to requirements of switching speed and efficiency.
