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.
