Webb13 juli 2011 · Similar to startup time/settling time, the PFD frequency and VCO gain play a key role in Jitter.Higher PFD frequencies mean that the PLL loop filter voltage is refreshed at a higher rate.This prevents the loop filter voltage from drifting.By using a large loop filter capacitance, the amount of voltage drift per PFD period is minimized.Because the VCO … Webb10 apr. 2024 · settling time bandwith. These times are mainly determined by the loop-bandwidth of your PLL. Large loop-bandwidth: small settling time but large in-band noise. Small loop-bandwidth: large settling time but good in-band noise. If the loop-bandwidth is about 200KHz, the settling time is about 10us. the loop bandwidth is too small. WebbIt is a type of controller formed by combining proportional and integral control action. Thus it is named as PI controller. In the proportional-integral controller, the control action of both proportional, as well as the integral controller, is utilized.
