Superconductive logic circuit

Patent ·
OSTI ID:5700464

A basic logic circuit of a superconductive logic circuit comprises a bridge circuit of four branches wherein first and second terminals are connected at least at two nodes and an output terminal is connected at least at a node. One branch of the bridge circuit comprises a series circuit consisting of a first resistor and a first Josephson junction connected between the first and second input terminals. The second branch comprises a parallel circuit of a second Josephson junction and a second resistor connected between the first input terminal and a grounding terminal of the bridge circuit. The third branch comprises a third resistor connected between the second input terminal and the output terminal. The fourth branch comprises a third junction connected between the output terminal and the grounding terminal. A load resistor is connected between the output terminal and the ground.
