This paper presents the design of an isolated gate driver system using a low volt-second differential pulse scheme to enable the use of a thin-film magnetics-on-silicon interleaved solenoid transformer. The transformer was designed for a CMOS compatible Back-End-of-Line (BEOL) process to ultimately enable monolithic integration with the gate driver. The design of a prototype custom 130 nm CMOS gate driver primary and secondary signal-coupling chipset around this transformer achieved operation with 10 V/ns gate driver signal pulses and transformer system.
