PURPOSE:To decrease the number of elements of a circuit itself and to reduce the stray capacity of a signal delay element by using one or plural two-input exclusive OR circuit composed of inverter circuits, a clocked gate circuit, and an analog switch circuit. CONSTITUTION:A two-input exclusive OR (NOR) circuit consists of inverter circuits 4 and 5 (204 and 205), a clocked gate circuit 6 (206), and an analog switch circuit 7 (207) and is equipped with input terminals 1 and 2 (101 and 102) and an output terminal 3 (203). In this case, 10 elements are used. This circuit is used to constitute a four-input exclusive OR circuit or eight-input exclusive OR circuit. The number of elements constituting the four-input exclusive OR circuit is 30 and the number of elements constituting the eight-input exclusive OR circuit is 70, so the number of elements of circuit configuration in this invention is less than before. |
