Abstract
This article presents a 6.78-MHz wireless power
transfer (WPT) system with system-level wireless hysteretic con-
trol technique and circuit-level designs for both the receiver (RX)
and transmitter (TX) chips. The proposed system achieves RX
local voltage regulation and TX global power regulation without
using any off-chip components (e.g., MCU, DAC, or various
controllers and decoders) nor TX current sensing coils, which
were required in previous works. A higher light-load efficiency
and instant
