ABSTRACT:
A reference signal enhancement device for phase lock loop oscillator. In the reference signal enhancement device, a band pass filtering unit is coupled to a reference signal to filter high frequency noise, low frequency noise, and harmonic components of the reference signal or components with frequency exceeding a predetermined frequency in the reference signal. A signal amplification device including three amplifiers connected in series is coupled to the band pass filter to convert the filtered reference signal.
