This paper presents a novel architecture for a highly efficient rectifier circuit that can be fully integrated using a standard CMOS process without special process options.Abstract:
This paper presents a novel architecture for a highly efficient rectifier circuit. The rectifier can be fully integrated using a standard CMOS process without special process options. The needed dynamic bulk regulation transistors are inherent in the first stage. A full wave rectifier with only one threshold voltage drop and an efficiency of approximately 50% is realized. In combination with a low-power active diode the proposed rectifier shows nearly no voltage drop and the efficiency rises up to 90%.read more
