Abstract
It is intended to provide an AD converter capable of increasing its conversion accuracy. An AD converter is equipped with a clock generator which generates a first clock using a second clock and a comparator which includes a comparison circuit for comparing an input signal with a prescribed value in a first period of the first clock and a precharging circuit for precharging, in a second period of the first clock, an internal voltage to a prescribed value for the next comparison operation. The clock generator includes a replica circuit of the precharging circuit of the comparator. In the replica circuit of the precharging circuit, a precharging period from the start to the end of precharging is set as the second period of the first clock.
