Abstract
A compound logic circuit including one NAND gate constituted by two p-channel transistors and two n-channel transistors and one NOR gate constituted by two p-channel transistors and two n-channel transistors. The compound logic circuit is characterized by one of the two p-channel transistors contained in the NAND gate being used as one of the two p-channel transistors contained in the NOR gate and one of the two n-channel transistors contained in the NAND gate being used as one of the two n-channel transistors contained in the NOR gate.
