A comparator includes: a CMOS inverter constituted by a combination of a first p-channel MOS transistor and a first n-channel MOS transistor; a second p-channel MOS transistor connected in parallel to the first p-channel MOS transistor in an analog input period, and disconnected from the first p-channel MOS transistor in a comparison period; and a second n-channel MOS transistor connected in parallel to the first n-channel MOS transistor in the analog input period, and disconnected from the first n-channel MOS transistor in the comparison period.
