  • Boosted-bias tunable filter with dynamic calibration
    Patent number: 7821362
    Abstract: In a signal communication device, a frequency-selective filter has at least one component that is biased by a control signal to establish a center frequency of the frequency-selective filter. A closed-loop bias generator is provided to generate the control signal and to adjust the control signal based, at least in part, on a comparison of the control signal and a reference signal.
    Type: Grant
    Filed: February 4, 2009
    Date of Patent: October 26, 2010
    Assignee: Telegent Systems, Inc.
    Inventors: Samuel W. Sheng, Michael Khitrov
