Abstract

Embodiments of methods and apparatuses may provide the capability to extend the tuning range of a VCO in a way that does not degrade VCO circuit performance. For example, the parasitic capacitance of semiconductor devices in the VCO circuit may be utilized to extend the tuning range of a VCO without significant degradation of VCO circuit performance. For example, in an embodiment, a method voltage-control of an oscillator may comprise receiving a first signal for control of a frequency of an output signal from the oscillator, deriving a second signal from the first signal, controlling the frequency of the output signal from the oscillator using the first signal, and extending a frequency range of the oscillator using the second signal.
