Integrated half-bridge circuit with low side and high side composite switches

Abstract

There are disclosed herein various implementations of an integrated half-bridge circuit with low side and high side composite switches. In one exemplary implementation, such an integrated half-bridge circuit includes a III-N body including first and second III-N field-effect transistors (FETs) monolithically integrated with and situated over a first group IV FET. The integrated half-bridge circuit also includes a second group IV FET stacked over the III-N body. The first group IV FET is cascoded with the first III-N FET to provide one of the low side and the high side composite switches, and the second group IV FET is cascoded with the second III-N FET to provide the other of the low side and the high side composite switches. The first and second III-N FETs are normally ON FETs, and the low side composite switch and the high side composite switch are normally OFF switches
