Abstract
Power consumption is reduced in an analog-to-digital conversion circuit using a TDC. The analog-to-digital conversion circuit includes a comparator, a counter, a time-to-digital converter, and a holding unit. The comparator compares an analog signal with a predetermined reference signal and outputs a comparison result. The counter counts a predetermined count value and outputs a bit string indicating the count value. The time-to-digital converter converts, into a digital signal, a time from when the comparison result is inverted until a least significant bit of the bit string reaches a predetermined value. The holding unit holds the bit string of when the comparison result is inverted.
