Abstract
The present invention provides an A/D converter includes: a plurality of comparators for comparing a plurality of respective standard voltages with an analog input value for a magnitude thereof, the comparators being arranged depending on magnitudes of the standard voltages; a logic boundary detector for detecting a logic boundary point where output signals from the comparators change from one level to another level; and a plurality of majority circuits for being supplied with the output signals from the comparators and determining output signals based on a majority vote on the output signals from the comparators, the majority circuits having logic threshold values adjusted for respective input terminals thereof which are supplied with the output signals from the comparators.
