The present invention relates to a method for controlling a voltage-controlled oscillator (VCO), which uses a control unit to produce a switching signal according to a counting signal for switching a plurality of current sources. The VCO receives the currents of the plurality of current sources and a reference current and produces an output frequency signal. Thereby, according to the present invention, the counting signal is used for controlling the currents of the plurality of current sources, and thus the frequency range of the output frequency signal can be controlled. The output frequency band of the VCO is broadened accordingly.
