  • Abstract
    The complete operation of a microprocessor prototype based on the single-flux-quantum (SFQ) logic is described. The 8b SFQ microprocessor, fabricated using niobium Josephson-junction technology, performs computation at a 15.2GHz clock rate with power consumption of 1.6mW. The μP contains 5000 Josephson junctions and 1300 cells on a 5mm2 IC.
