Abstract
An integrated circuit comprises plural superconducting circuit blocks connected through superconducting wiring strips, and each superconducting circuit block includes at least one superconducting logic circuit, constant input/output circuits connected between the input/output nodes of the circuit block and the superconducting logic circuit; parameters of the constant input/output circuits are regulated such that statically flow-in/flow-out current is approximately equal to zero at the input/output nodes of the superconducting logic circuit, whereby the superconducting logic circuit operates at the optimum operating point after the integration.
