摘要： The invention provides a PLL device comprising a PFD unit, a charging pump circuit, a loop filter, an oscillator, a feedback divider and a current compensation circuit. The PFD unit measures a phase and a frequency difference between a reference clock signal and a feedback clock signal of the PLL device to output a difference signal UP and a difference signal DN. The charging pump circuit receives and transfers the difference signals UP and DN into a current. The loop filter receives and transfers the current into a voltage. The oscillator receives the voltage and outputs an output signal. The feedback divider having a parameter N receives the output signal to generate the feedback clock signal according to the parameter N, wherein a frequency of the feedback clock signal is N times a frequency of the output signal. When the reference clock signal leads the feedback clock signal, the current compensation circuit outputs a compensation current to the loop filter.
