Abstract: A rectifying circuit is provided, which includes a first channel circuit, a comparator circuit, and a second channel circuit. The first channel circuit rectifies a first input signal using a transistor that is coupled between an input of the first channel circuit and a node. The comparator circuit is coupled with the transistor and controls it based on a difference between a representative voltage of the first input signal and a representative voltage of the node. The second channel circuit rectifies a second input signal using a diode coupled between an input of the second channel circuit and the node. The transistor may be a first MOSFET and the comparator circuit may be coupled with the first MOSFET by way of a second MOSFET. The second MOSFET controls the first MOSFET and is itself controlled by the comparator circuit.
