    摘要: A PLL circuit includes a phase detector that compares the phase of an input clock and the phase of a feedback clock and generates a pull-up control signal and a pull-down control signal. A loop filter pumps a voltage in response to the pull-up and pull-down control signals, filters the pumped voltage, and outputs a control voltage. A voltage controlled oscillator receives the control signal and oscillates an output clock. A clock divider divides the frequency of the output clock at a predetermined rate to generate the feedback clock. In the PLL circuit, the loop filter includes a compensator that compensates for a variation.
