ABSTRACT:
In a voltage comparator circuit, among first and second signal voltages to be compared, the first signal voltage is input to a first input terminal of a differential voltage comparator through a first switched capacitor circuit, and the second signal voltage is input to a second input terminal of the differential voltage comparator through a second switched capacitor circuit. In the voltage comparator circuit, the first and second switched capacitor circuits are matched with each other.
