Abstract
In a voltage comparator, a positive feedback circuit having first and second inverters compares the potential of the input terminal of the first inverter with the potential of the input terminal of the second inverter and outputs the comparison result from the output terminal of the second inverter. A first input circuit supplies the first potential corresponding to an input comparison voltage to the input terminal of the second inverter. A second input circuit supplies the second potential corresponding to an input reference voltage to the input terminal of the first inverter. A control circuit supplies a power supply voltage to the positive feedback circuit when an input control signal represents a comparison operation period to execute voltage comparison operation. When the control signal represents an initialization period, the control circuit stops supplying the power supply voltage to set an initial state. A first reset circuit reduces the first potential to a ground potential when the control signal represents the initialization period. A second reset circuit reduces the second potential to the ground potential when the control signal represents the initialization period.
