Patents by Inventor Michael Angelo Tamburrino

Michael Angelo Tamburrino 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).

  • MOS transistor with serrated gate structures
    Patent number: 7023032
    Abstract: A digital power supply system provides a supply voltage to semiconductor circuits. The power supply system utilizes a pulse width modulator to output a signal into a LC filter that generates a DC supply voltage. The width of the pulses output by the pulse width modulator are defined by an encoder that generates width information in response to a propagation delay detector that measures the propagation delay of a first clock signal when clocked by a second clock signal.
    Type: Grant
