    Abstract

    This paper presents a sub-0.3V CMOS full-wave rectifier for energy harvesting devices. By adopting a body-input comparator with simple bias circuit and body bias technique, the lowest input voltage amplitude can be reduced to 0.28V when using a standard CMOS 0.18μm process. The voltage drop of negative voltage converter can be reduced to enhance the output voltage by the body bias technique. In combination with the proposed comparator with minimum reverse current, the proposed active rectifier can achieve the peak voltage conversion efficiency of over 96 % and the maximum power efficiency near to 94 %.
