  • Methods and apparatus to implement receiver linearity enhancement
    Patent number: 8045941
    Abstract: Methods and apparatus to implement receiver linearity enhancement are described. One example method includes controlling receiver gain by determining a level of a received signal that is to be provided to a radio frequency component; determining if the level of the received signal would cause the radio frequency components internally generated noise to increase; and when the level of the received signal would cause the radio frequency components internally generated noise to increase, reducing the level of the received signal prior to providing the received signal to the radio frequency component.
    Type: Grant
    Filed: August 29, 2007
    Date of Patent: October 25, 2011
    Assignee: Texas Instruments Incorporated
    Inventors: Khurram Muhammad, Chandana Fernando
  • System and method for amplifier gain measurement and compensation
    Patent number: 7639082
    Abstract: A system and method for amplifier gain measurement and compensation. A method for compensating a signal gain of an amplifier circuit includes determining a desired gain for the amplifier circuit, determining an operating temperature of the amplifier circuit, adjusting a set of signal gains based on the operating temperature to produce a set of adjusted signal gains, determining a desired gain setting based on the desired gain and the set of signal gains, and providing the desired gain setting to the amplifier circuit.
