    Abstract

    This paper presents a low voltage CMOS full-wave rectifier for wirelessly powered devices. By using a simple comparator-controlled switch, the lowest input voltage amplitude can be reduced to 0.7V when using a standard CMOS 0.18μm process. With only one comparator, the proposed design dramatically reduces the production cost. In combination with unbalanced transistor scale, the proposed rectifier can achieve a maximum peak voltage conversion efficiency of more than 93% and power efficiency near to 87%.
