Kumen E. Blake 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).

  • Multi-channel amplifier having programmable operational characteristics controlled with a serial interface
    Patent number: 7505855
    Abstract: An amplifier having programmable operational characteristics and a serial communications interface is fabricated on an integrated circuit (IC). The serial communications interface controls the operational characteristics, e.g., gain, frequency response, etc., of the amplifier. A multiplexer (MUX) may also be included on the IC and may be controlled by the serial communications interface. Status of the amplifier may also be obtained through the serial communications interface. The pin count of the IC package may be kept to a minimum by using the serial communications interface.
    Type: Grant
    Filed: January 21, 2005
    Date of Patent: March 17, 2009
    Assignee: Microchip Technology Incorporated
    Inventors: Kumen E. Blake, James B. Nolan
  • Multi-channel programmable gain amplifier controlled with a serial interface
    Patent number: 6847904
    Abstract: A programmable gain amplifier (PGA) controlled through a serial communications interface are fabricated on an integrated circuit (IC). A multiplexer (MUX) may also be included on the IC. The serial communications interface controls the gain of the PGA, MUX channel selection, and other functions of the PGA. Status of the PGA may also be obtained through the serial communications interface. By using a serial communications interface, the pin count of the PGA IC package may be kept to a minimum.
