A chip-to-chip inductive wireless power transmission system is proposed and the feasibility is experimentally demonstrated for the first time. The circuit realized 2.5mW power transmission at the output DC voltage of 0.5V using 700 times 700mum on-chip planar inductors for the transmitter and the receiver. Methods to optimize the circuit design about the maximum transmission power and the simulated optimization results are discussed
