Abstract

The present application discloses a voltage-controlled oscillator device and a method of correcting the voltage-controlled oscillator. The voltage-controlled oscillator device comprises predistortion module, configured to predistort an input voltage to obtain a predistorted voltage; and a voltage-controlled oscillator, configured to generate an output signal with a corresponding oscillation frequency according to the predistorted voltage, wherein the predistortion module corrects a non-linear characteristic of the voltage-controlled oscillator, so that there is a linear relationship between the input voltage and the oscillation frequency of the output signal. The voltage-controlled oscillator device may be applied to a phase-locked circuit in a communication system.
