Abstract
A voltage-controlled oscillator comprising a voltage compensation transistor is disclosed. The voltage compensation transistor is able to provide an equivalent resistance to the bias voltage supplied to the oscillator. When a sudden raise in the voltage of the power supply takes place, the equivalent resistance of the compensation transistor will drop, such that the bias voltage supplied to the oscillator may be pulled down, whereby the oscillation frequency of the ring oscillator may be adjusted.
