PURPOSE:To obtain a superconduction loop logical circuit suitable for circuit integration, by providing a superconduction loop magnetically coupled with input lines and driving a Josephson circuit with an induced current due to an input signal. CONSTITUTION:A superconduction loop 1 has inductances 2-4 of 100pH, input lines 5, 6 are provided in interlinking with the wiring of the said loop 1 and linked to the loop 1 with 90pH of inductance. A gate current is applied from a terminal 9 to a Josephson junction 7 forming a convert circuit together with a load 8 and a bias current is applied from a terminal 10. The junction 7 is driven via the loop 1 through the presence/absence of the current of the input lines 5, 6 and in case of the circuit shown in figure, it has a function of an AND circuit. Various logical circuits can be constituted by changing the linking method between the input lines and the superconduction loop in this invention. |
