Phase lock loop, voltage controlled oscillator of the phase lock loop, and method of operating the voltage controlled oscillator
A voltage controlled oscillator (VCO) includes a sensing circuit, where the sensing circuit is configured to generate a plurality of compensation control signals. The VCO further includes a voltage-to-current converter comprising a plurality of current sources which are configured to generate a current signal in response to the plurality of compensation control signals. Additionally, the VCO includes a plurality of switching circuits, each of the plurality of switching circuits being configured to selectively enable or disable a corresponding one of the plurality of current sources in response to a corresponding one of the plurality of compensation control signals. Furthermore, the VCO includes a current controlled oscillator configured to generate an oscillating signal in response to the current signal.
