Dear antia66,1 l) `$ c- P. g4 Z8 Y
If damping factor is choosen 2, how about the natural freqency?4 u- Z* g Z. V5 N
Will the natural freqency changed with damping factor ?
n7 @" `, S) ^0 ^- q5 aAs my understanding, choose bandwidth <= 1/10*reference freq is for linear model is valid or not, that is, if need widther bandwidth PLL, the parameter from continuous model cannot provide expected PLL behavior. b# T, ]7 i' g2 L0 z+ [
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
