  • Digitally controlled oscillator
    Patent number: 7336134
    Abstract: A tunable oscillator suitable for use in a frequency synthesizer of a transceiver is controlled by varying one or more parameters associated with the oscillator. In particular, a digital control signal affects one or more of the capacitances of the oscillator, the bias voltage of the oscillator, the supply voltage, or the bias current of the oscillator. Changes to one or more of these parameters allows the frequency of the oscillator to be controlled as desired.
