  • Abstract
    New elements of the rapid single flux quantum (RSFQ) logic family have been designed, fabricated, and tested. All-Nb 14-layer 5 μm technology using externally shunted tunnel junctions with jc=500 A/cm2, IcR s=300 μV, and Bc⩽1 has been used. The T-flip-flop circuit has been demonstrated to operate with ±30% margins at clock frequencies below 50 GHz and with at least ±10% margins at frequencies up to 120 GHz. Operation of the input (DC/SFQ) and output (SFQ/DC) converters ±40% margins is also demonstrated
