Abstract
Aspects of the disclosure provide a voltage controlled oscillator. The voltage controlled oscillator can include a plurality of oscillation stages coupled together to generate an oscillation signal having an oscillation frequency. At least one oscillation stage of the plurality of oscillation stages can include a first portion driven by a first driving power that can be a function of a control voltage and a second portion driven by a second driving power that can be substantially independent of the control voltage. The first driving power can be provided by a first power rail in the form of a driving current that is a function of the control voltage. The second driving power can be provided by a second power rail in the form of a substantially constant voltage that is substantially independent of the control voltage.
