- Abstract
- This paper presents an adaptive dead-time control for the zero-voltage switching operation of a wireless power amplifier to improve efficiency. In this paper, a power amplifier is designed using a differential class-D structure for high efficiency and maximum output power. The proposed circuit enables zero-voltage switching operation of the power amplifier through a controller that detects various system parameter changes and adaptively adjusts the dead-time. The proposed circuit is fabricated in a CMOS 180-nm standard process. The proposed dead-time control system for zero-voltage switching is verified through the simulation result.
