Abstract

In this paper, a 13.56 MHz power-efficient CMOS active rectifier is proposed for implantable medical devices. The digital offset compensation technique automatically compensates the turn-off delay to minimize the reverse leakage current to improve the conversion efficiency. The simulation results show that the proposed rectifier achieves 92.9% PCE with wide input voltage range. The input operating voltage ranges from 1.5V to 4.5V and the efficiency improvement of 6.5% is also obtained.
