  • Oscillator system, method of providing a resonating signal and a communications system employing the same
    Patent number: 7692504
    Abstract: An nth-order oscillator system for providing a resonating signal, a method of generating a resonating signal and a communications system. In one embodiment, the nth-order oscillator system, n being greater than two, includes (1) an amplifier configured to provide an intermediate signal and (2) a feedback loop including an nth-order complex LC tank and configured to generate the resonating signal by feeding back a complex-filtered form of the intermediate signal to the amplifier.
    Type: Grant
    Filed: February 12, 2008
    Date of Patent: April 6, 2010
    Assignee: Texas Instruments Incorporated
    Inventors: Chih-Ming Hung, Robert B. Staszewski, Dirk Leipol
