Matthew R. Cordrey-Gale 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).

  • Variable gain amplifier
    Patent number: 7852151
    Abstract: A method of varying the gain of an amplifier and an amplifier array are provided. The amplifier array includes two or more amplifier stages (201, 202) connected in parallel with each amplifier stage having a gain control means. Input signal means (203, 204) are provided for each amplifier stage with the input signals of the amplifier stages being of different amplitude. Means for enabling and disabling an amplifier stage (216) are provided and means for summing the outputs of the enabled amplifier stages obtain an output signal (212).
    Type: Grant
    Filed: May 30, 2008
    Date of Patent: December 14, 2010
    Assignee: International Business Machines Corporation
    Inventors: Thomas J. Bardsley, Matthew R. Cordrey-Gale, James S. Mason, Philip J. Murfet, Gareth J. Nickolls
