COMPARATOR CIRCUIT, COMPARATOR CIRCUIT CONTROL METHOD, A/D CONVERSION CIRCUIT AND DISPLAY UNIT

摘要

PROBLEM TO BE SOLVED: To provide a comparator circuit, a comparator circuit control method, an A/D conversion circuit and a display unit having the comparator circuit capable of reducing power consumption by optimizing the power consumption according to the operation state of a differential circuit.SOLUTION: The comparator circuit includes: a differential circuit that detects a difference between two input signals; a current supply section that supplies a current to a differential circuit; and a control section that detects operation timing of the differential circuit and controls the current supplied to the differential circuit by the current supply section according to the detection result.
