| 摘要 | An arithmetic processing apparatus or circuit for performing charge redistribution by one or more capacitances connected to an input portion of each comparator are realized with improved arithmetic accuracy as suppressing dispersion and errors of gains of signals input into comparators, in such an arrangement that as the arithmetic processing apparatus is arranged to have a plurality of comparators, each having one or more capacitances connected to the input portion thereof, a sum of the capacitors connected to the input portions of each comparators 71 (or 72), C 11 +•••+ C 1n (or C 81 +•••+ C 8m ), is substantially equalized among the plurality of comparators, or a ratio of the sum of the capacitors connected to the input portion of each comparator 71 (or 72), C 11 +••• + C 1n (or C 81 +•••+ C 8 m ), and input capacitance C p1 (or C p2 ) of the comparator is substantially equalized among the comparators. | ||||||
