Abstract

An analog/digital converter includes: a ramp signal generation circuit that generates a ramp signal; a comparison circuit that compares potential of an input analog signal with potential of the ramp signal and outputs a comparator output signal if the potential of the ramp signal satisfies the predetermined condition; a count control circuit that divides a predetermined ramp period in which the ramp signal generation circuit outputs the ramp signal into a predetermined number n of divided ramp periods and outputs a count-stop signal; a counter circuit that counts time in the divided ramp period and outputs a count value of the counted time; and a decoder circuit that generates a digital signal according to a count value and a digital value corresponding to any one of the divided ramp periods in which the counter circuit has started counting of time and outputs the generated digital signal.
