  • Integrated logic MOS counter circuit
    Patent number: 4433372
    Abstract: A multi-stage logic circuit employing integrated MOS-circuit techniques having gates to produce carry signals between stages where the gates which transfer the carry signals are designed as transfer-gates. Specific circuits are shown for full adders, comparators, synchronous binary counters, forwards-backwards synchronous binary counters and forwards-synchronous counting decades.
    Type: Grant
    Filed: December 15, 1981
    Date of Patent: February 21, 1984
    Assignee: Siemens Aktiengesellschaft
    Inventors: Dieter Eichrodt, Friedhelm Elsen
