This paper presents a 6.78-MHz single-stage regulating rectifier with hysteretic control and current-wave modulation (CWM) techniques for wireless power receiver applications. The proposed receiver realizes AC-DC rectification and DC-DC regulation in a single power stage, thus improving the power efficiency and reducing the system volume. The hysteretic control together with the proposed CWM technique achieves a much accelerated load-transient response for the rectifier compared to the recently developed multi-cycle pulse width modulation (PWM) techniques. The system design complexity is significantly reduced. The proposed multi-level CWM technique achieves more evenly distributed power conversions and less output voltage ripples. The proposed receiver fabricated in a 0.18-μm CMOS process using 3.3-V devices, can regulate the output voltage to 3.3 V and deliver 1.98-W maximum power with a measured peak efficiency of 92.14%. An instant load-transient response is observed for a load current step between 12 mA and 600 mA.
