ABSTRACT:
A logic operation circuit includes an exclusive-OR circuit for receiving first and second logic sum signals of preceeding stages, a sum signal selection circuit for selectively generating a carry output signal or an inverted signal thereof as a carry output signal in accordance with an output signal from the exclusive-OR circuit, and a carry output signal selection circuit for selectively generating the carry input signal or the first logic sum signal as a sum signal in accordance with the output signal from the exclusive-OR circuit. The exclusive-OR circuit includes a double balance type differential amplifier connected between first and second power source terminals, and the sum signal selection circuit includes a double balance differential amplifier operated in accordance with the output signal from the exclusive-OR circuit and the carry input signal and connected between the first and second power source terminals.
