Abstract:
A comparator circuit includes a differential circuit unit which detects a difference between two input signals, a current supply unit which supplies a current to the differential circuit unit, and a control unit which detects an operation timing of the differential circuit unit and controls the current supplied to the differential circuit unit by the current supply unit according to a detection result thereof.
