Abstract
A wireless power telemetry with self-calibrated resonant frequency is presented. The proposed calibration scheme adjusts the resonant frequency of inductively secondary coil to match the incident frequency of inductively primary coil. To adjust the resonant frequency of the secondary coil, the received power efficiency is improved. By experimented results, the overall power efficiency with frequency calibration is improved by a factor of 33%, compared with that one without frequency calibration. This wireless power telemetry has been fabricated in a standard 0.35µm CMOS process, and the chip area is 1.536mm 2 including I/O pads.
