Integrated circuit of superconducting circuit blocks and method of designing the same

摘要

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.
