Abstract

The problem of the disclosed technology is as follows. Although a single flux quantum circuit can fabricate a high-speed sequential circuit with ease, the initialization of the circuit is required for guaranteeing the normal operation of the circuit. However, a prior-art circuit has no initializing function, or requires the restructuring of another logic system. For solving the foregoing problem, one Josephson junction is inserted to a flux quantum storage inductor constituting the existing logic circuit, so that a pulse for performing the circuit initialization is injected to the connection point by means of a comparator.
