N2 - Fixed dead-time controlling strategy is widely adopted in conventional converter design, while it suffers from the potential issue of simultaneous conduction under different loading conditions. This work aims to adaptively optimize the dead-time at the monolithic integration level through simulation software, Advanced Design System (ADS). In a 48 V GaN buck converter, the sub-20-ns adaptive low-side dead-time control and high-side dead-time control are achieved at 1 MHz operation frequency. The proposed dead-time control circuit exhibits a maximum efficiency up to 91.4 %, facilitated by the adaptive and self-generated dead-time design.
