Abstract:
1. An integrated half-bridge circuit including a low side composite switch and a high side composite switch, said integrated half-bridge circuit comprising: 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; a second group IV FET stacked over said III-N body; said first group IV FET cascoded with said first III-N FET to provide one of said low side and said high side composite switches, and said second group IV FET cascoded with said second III-N FET to provide the other of said low side and said high side composite switches; wherein said first and second III-N FETs are normally ON FETs, and wherein said low side composite switch and said high side composite switch are normally OFF switches.
