    摘要: A phase locked loop frequency synthesizer including a phase locked loop, a frequency regenerator and a modulation processor, resistant to distortion induced by the frequency regenerator and conforming to transmission specifications. The phase locked loop comprises a detector generating a phase detection signal based on phase difference between a reference signal and a feedback signal, a loop filter, a voltage control oscillator generating a first output modulation signal and a frequency dividing unit varying a division factor based on a processed input modulation signal and dividing the frequency of the first output modulation signal by a division factor to generate the feedback signal. The frequency regenerator generates a second output modulation signal with a frequency range not overlapping an output frequency range of the voltage control oscillator. The modulation processor generates the processed input modulation signal to adjust the division factor of the frequency dividing unit and compensating for distortion induced by the frequency regenerator.
