  • Multi-frequency band controlled oscillator
    Patent number: 6650196
    Abstract: A variable frequency output signal is generated in response to a control signal by providing an oscillator (50) that generates the output signal in different frequency ranges depending on the value of an operating parameter, such as DC bias current. A first circuit (60) adjusts the operating parameter values and a second circuit (80) controls the Kvco of the oscillator.
    Type: Grant
