    Abstract

    In this paper, a 13.56 MHz fully-integrated wireless power transfer system with wireless constant-idle-time control is proposed. The massive off-chip components or wire required for transmitter (TX) voltage regulation in previous works are eliminated. Both wireless and local regulations are achieved with enhanced transient performance and total efficiency, and reduced circuitry and system design complexity. Thanks to the proposed wireless constant-idle-time control technique, an instant load-transient response, and a peak total efficiency of 67.6% with up to 13.7% improvement are observed in measurements with meat between coils at a distance of 6mm.
