Patents by Inventor Rudolph J. Hofmeister

Rudolph J. Hofmeister 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).

  • Transceiver module with voltage regulation and filtering
    Patent number: 7509051
    Abstract: An integrated circuit for use at a reduced Vdd voltage. An integrated circuit is designed and implemented such that it is usable at a voltage less than an industry standard Vdd voltage. The integrated circuit may include a voltage filter that may either be implemented on the integrated circuit or external to the integrated circuit. The voltage filter receives an industry standard IC voltage and produces a filtered voltage that is that some value below the industry standard IC voltage. The voltage filter also removes noise from the industry standard IC voltage. The integrated circuit includes signal processing circuitry that is designed and implemented to improve signal quality and to operate at the filtered voltage.
    Type: Grant
