摘要：
The invention provides a phase-locked loop (PLL). Since a loop bandwidth of the PLL is a function of a gain of a phase detector and a gain of a voltage controlled oscillator (VCO), by adjusting the gain of the phase detector, the variation of the gain of the VCO (i.e., the tuning sensitivity) is compensated, so that the loop bandwidth of the PLL becomes more stable.
