Abstract

A circuit utilizing Josephson junctions to perform high speed logic gate switching functions. Three 'Y' connected resistors have Josephson junction devices at their non-connected ends. The resistances of the resistors, the critical currents of the Josephson junctions, and the amplitudes of input currents to two of the resistor-Josephson junction connections are selected so that, when the input currents are applied at the same time, the third Josephson junction is switched to the voltage state and both input currents are derived from the third Josephson junction-resistor connection as an input current. In another embodiment, the basic circuit has additional resistor-Josephson junction input arms, producing an M/N logic gate function. In another embodiment, the resistors are '.DELTA.' connected. The resulting logic gates have wide operational margins, high speed switching capabilities and small size.
