摘要
A voltage controlled oscillator (VCO) includes a current controlled oscillator, a voltage-to-current converter, and a sensing circuit. The sensing circuit includes a delay unit, and the sensing circuit is configured to generate a plurality of compensation control signals in response to a time delay of the delay unit. The voltage-to-current converter is configured to generate a current signal in response to a VCO control signal and the plurality of compensation control signals. The current controlled oscillator is configured to generate an oscillating signal in response to the current signal.
