Abstract

Superconducting timed gate array cells for use in single-rail logic circuits are provided by adding inputs to modified variable threshold logic (MVTL) timed inverter circuits. Data signals which are inphase with a first phase of a power source are coupled to gate array cells in which Josephson junction bias current is provided by a second phase of the power source. NOR, NAND, 2NOR-OR and 2NAND-AND circuits are disclosed for use as building blocks in the production of specialized digital logic circuits.
