  • METHOD AND APPARATUS TO CONTROL THE LC TANK TEMPERATURE NULL CHARACTERISTIC IN A HIGHLY STABLE LC OSCILLATOR
    Publication number: 20130314167
    Abstract: A substantially temperature-independent LC-based oscillator uses bias control techniques. Temperature independence may be achieved by controlling the harmonic frequency content of the output of the oscillator by controlling the amplitude. Amplitude control may be achieved by inserting a control mechanism in the feedback loop of the oscillator.
