High efficient rectifier circuit eliminating threshold voltage drop for RFID transponders

Abstract

A high efficient rectifier circuit eliminating threshold voltage drop is presented. Based on conventional full wave bridge rectifier circuit, this rectifier circuit uses bootstrapped circuit technique, so it conquers the problem of threshold voltage drop in conventional rectifier circuit. The characteristic of high efficiency and compatibility with standard CMOS process make the rectifier circuit suitable for RFID transponders where high efficient rectifier circuit is much required
