Abstract
According to one embodiment, an A/D converter includes a first delay cell column in which a plurality of delay cells, to which a first bias current corresponding to a difference voltage between an input voltage and a reference voltage is supplied, is connected in series. The converter includes a second delay cell column in which a plurality of delay cells, to which a second bias current corresponding to a negative-phase difference voltage of the difference voltage is supplied, is connected in series. The converter includes an encoder unit configured to encode a difference value, in delay time of signal propagation, between the first delay cell column and the second delay cell column.
