Then the input A and the signal A' are connected to the drains of both FETs 72 and 74 respectively. Thus the number of transistors is decreased and a high degree of integration is attained. Accord ing to a real value table, Ci=Ai is satisfied when the exclusive OR of inputs Ai and Bi is equal to '0'. Then Ci=Ci-1 is satisfied when said exclusive OR is equal to '1'. Thus a carry output Ci is produced at a high speed by switching Ai and Ci-1 with the output signal of the exclusive OR of Ai and Bi used as a control signal.
