An A/D converter includes a plurality of comparators, each of which samples an analog input potential during a first period, and compares the analog input potential with a reference potential during a second period, an encoder which encodes comparison results obtained by the comparators, and a control signal supply unit which generates one or more control signals that define the first period and the second period such as to make a duration of the first period different from a duration of the send period, and supplies the one or more control signals to the plurality of comparators.
