ABSTRACT:
A Josephson junction AND gate logic circuit is provided which has an enhanced and improved operating window area. The circuit comprises two parallel branches one for the input and one for the output connected between a biasing current source and a ground or reference voltage. The input branch is provided with a first branch resistor, a third Josephson junction and an interferometer in series between the current source and ground. A plurality of input gate signal lines connects to the interferometer and a sink resistor is connected in parallel with the interferometer. When the input current signals collectively exceed a predetermined level, the two Josephson junctions in the interferometer switch ON and assume the high impedance state. The input current and biasing current is diverted into the output branch causing the second Josephson junction in the output branch to switch ON. The biasing current in the output branch creates a high-gain current to the load circuit connected in parallel with the second Josephson junction.
