Abstract

PURPOSE:To realize the simplification of constitution, low power consumption and high-speed working of the function each, by using four Josephson elements, four inductance elements plus one impedance element each. CONSTITUTION:The exclusive logic sum circuit consists of asymmetric quantum interference type circuit G1 (comprising Josephson elements J1 and J2, inductance elements M1 and M2 plus impedance element R each) and asymmetric quantum interference type circuit G2 having the same structure (comprising Josephson elements J1 and J2 plus inductance elements M1 and M2 each). And parallel circuits Q of circuits G1 and G2 are connected in series to be inserted to bias current line B, and furthermore input current lines D1 and D2 are connected electromagnetically to elements M1 and M2 of circuit Q in circuit G2 respectively. In such constitution, logic output signal Z(IF) is obtained only in case either logic input signal X(IC1) or Y(IC2) is ''1'' to secure the function as an exclusive logic sum circuit.
