Abstract
A rectifier circuit is configured to receive first and second alternate current (AC) signals that have opposite phases. The rectifier circuit includes a first half-wave rectifier circuit that includes a first metal-oxide-semiconductor (MOS) transistor and a second MOS transistor connected in series, and performs half-wave rectification on the first AC signal to generate a first direct current (DC) signal, a second half-wave rectifier circuit that includes a third MOS transistor and a fourth MOS transistor connected in series, and performs the half-wave rectification on the second AC signal to generate a second DC signal, the first DC signal and the second DC signal being outputted by the rectifier circuit to a load, and a body potential setting circuit configured to set a body potential of each of the first MOS transistor, the second MOS transistor, the third MOS transistor, and the fourth MOS transistor.
