Patents by Inventor Ronald J. Yepp

Ronald J. Yepp has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6693457
    Abstract: An ultra high speed Emitter Coupled Logic (ECL) flip-flop is provided and a method of operating the same. The ECL flip-flop provides for clock levels that operate at logic levels above the data levels. Since the clock operates at logic levels above the data, the clock experiences level shifts that are less than the level shifts of the data. Therefore, the clock will provide a higher fidelity signal relative to the conventional clock signal. The ECL flip-flop can operate at significantly higher data rates than conventional flip-flop circuitry.
    Type: Grant
