Abstract
Technology regarded to an electric circuit, particularly a zero current detection circuit, is disclosed. The proposed zero current detection circuit has a calibration circuit that calibrates an offset error thereof. The offset calibration circuit detects a delay between an output time point of the zero current detection circuit and a moment of change in voltage of the common node and outputs a calibration signal accordingly. The zero current detection circuit includes a pre-amplifier that calibrates a differential voltage according to an offset control signal and a phase comparator that detects a zero current point from the differential voltage.
