FREQUENCY CORRECTION SYSTEM AND CORRECTING METHOD THEREOF

摘要

The present invention provides a frequency correction system. The frequency correction system includes: an oscillator outputting a target signal including an oscillation frequency; and a frequency compensator correcting the oscillation frequency to be matched to a frequency of a reference signal by comparing the frequency of a target signal to the frequency of a preset frequency signal. Therefore, the frequency correction system can provide a precise and stable oscillation frequency by automatically correcting an error of the oscillation frequency generated by a manufacturing process.
