该论文提出了一种无线功率传输系统，通过全集成设计实现了高达20%的轻载效率提升和快速动态响应，解决了现有WPT系统在轻载条件下效率低和瞬态响应慢的问题。
Wireless power transfer (WPT) systems are becoming increasingly popular for sub100mW biomedical applications [1-5]. Because the received power is sensitive to coupling and loading conditions, power/voltage regulations are essential to achieve stable and accurate power delivery, fast transient response, and high end-to-end (E2E) efficiency, which includes all the power losses in the transmitter (TX), wireless power link, and the receiver (RX). Many existing WPT designs operated in open-loop [3-5]; or achieved voltage regulation but only in the RX [6], with the TX remained unregulated and designed to operate at full capacity, thus degraded E2E efficiency at light-load conditions. Because lower-power or standby mode typically contributes to the majority of the operation time, light-load efficiency is always an important specification of power management circuits, especially to extend the run time for battery-powered devices,
