The present invention discloses a voltage-controlled oscillating apparatus to generate an oscillating signal. The voltage-controlled oscillating device includes: a regulating circuit, a biasing circuit, and an oscillator. In which the regulating circuit includes an amplifier, with a first input terminal coupled to a control voltage; and a voltage adjusting circuit, coupled between a second input terminal and an output terminal to feed a feedback voltage back to the second input terminal of the amplifier, and adjust the feedback voltage according to the output signal in the output terminal of the amplifier. The biasing circuit is coupled to the output terminal of the amplifier to generate a biasing signal according to the output signal in the output terminal of the amplifier; and the oscillator is coupled to the biasing circuit to generate the oscillating signal according to the biasing signal.
