Abstract

This paper presents a full wave active rectifier for biological implanted devices using a new original comparator to reduce the rectifier transistors reverse current. The rectifier was designed in 0.13µm CMOS process and it can deliver 1.09Vdc when receive a minimum signal of 1.2Vac. It achieves a power conversion efficiency of 81% when working at 13.56MHz Scientific and Medical (ISM) band.
