Abstract
A comparator circuit according to the present disclosure includes a first switch section that selectively takes in a signal voltage, a second switch section that selectively takes in a control waveform, a differential amplifier including a non-inverted input end connected to each of output ends of the first switch section and the second switch section, a capacity section including one end connected to an inverted input end of the differential amplifier and the other end supplied with a reference voltage, and a third switch section that selectively short-circuits the inverted input end and an output end of the differential amplifier.
