Abstract: PURPOSE: By including the averaging circuit of the Mobius band form and reassigning a plurality of analog blocks it linear, the A/D converter can minimize error. CONSTITUTION: In the comparator array(22), each compares one reference voltage and analog data among a plurality of reference voltages. The comparator array comprises a plurality of comparators for outputting the logic signal based on the comparison result. The averaging circuit(23) comprises a plurality of metal routings for recompensing the offset generating from at least a part of logic signals. It is each other contiguous among both ends of the comparator array to one and the comparator in which the minimum standard voltage is inputted and the comparator in which the maximum reference voltage is inputted are arranged.
