A Modern High Efficient Full Integrated CMOS Rectifier for Wireless Power Transfer in Biomedical Application

in this paper is suggested a modern of full-wave rectifier in CMOS technology with high efficient for wirelessly powered devices. This is rectifier include simple structure withlow power consumption and low voltage drop. Number of fewer transistors in this circuit has low power consumption.This new topology leads to a very high efficiency for theproposed rectifier. The maximum output voltage and current in |Vin|=5V reach to 4.735v and 13.8mA respectively, whichmakes it ideal for using in biomedical applications and also human bodies’ implantable chips. This new proposed rectifierin |Vin|=5V reached to 92.18% for power efficiency and 64.2% for voltage efficiency. This rectifier designed and simulated in 0.18um CMOS technology by Hspice software.
