A highly efficient fully integrated passive CMOS rectifier is proposed in this paper. Using four ultra low power and low voltage techniques with proper leakage current compensation technique, this new topology is very high efficient in wide input voltage range of both high voltages and low voltage advanced sub-micron applications simultaneously. In 0.5V AC input signal amplitude the power and voltage transmission efficiency are 58% and 62% respectively and these values reach to 68% and 72% in 0.8V. Unlike the recently proposed rectifiers, in this new rectifier, for wide range of AC input signal amplitude the power and voltage transmission efficiency are higher than 90%. New proposed rectifier is applicable for bio-implantable systems with high current demands. The new full-wave rectifier also simulated and optimized only for low voltage advanced sub-micron applications. This rectifier designed and simulated in 0.18μm standard CMOS technology.
