A disclosed analog-to-digital converter includes； a sampling circuit to sample a pair of analog signals as a differential input signal； a binary capacitance holding the sampled pair of analog signals and reflecting a level of a reference signal to the analog signals through the binary capacitance to generate a pair of voltage signals； a comparator including a transistor to which the voltage signals are input, to compare one of the voltage signals with the other； a correction circuit provided previously to the comparator, to output to the comparator the pair of voltage signals in which voltage dependency of stray capacitance in the input transistor is cancelled； and a controller that successively determines a value of each bit of a digital signal corresponding to the binary capacitance based on a comparison by the comparison circuit, and reflects the value of each bit of the digital signal to the reference signal.
