Abstract	The design of a Resonant Regulating Rectifier (3R) capable of switching-mode operation is presented. The proposed 3R is a highly efficient receiver circuit intended for use in Resonant Wireless Power Transfer (RWPT) application with a 6.78 MHz resonant frequency. Owing to the inductance of resonant coils, the 3R does not require any additional inductor for the switching-mode regulation. The transmitted power via the RWPT with the 3R ranges from 0 W to 6 W, and its peak efficiency reaches 86%. It employs the Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) for different output power levels. This helps to increase the output power and to lower the voltage stress on the transistor. Fabricated in 0.35 μm BCD technology, the 3R circuit occupies an area of 2.35×2.35 mm². The functionality of the 3R is successfully demonstrated using a transmitter circuit with resonant coils.
