Dear antia66,
) |: n) H$ _% {. _- R qIf damping factor is choosen 2, how about the natural freqency?5 i* d' i7 g6 N. J. q
Will the natural freqency changed with damping factor ?
0 K# M$ J: y+ K/ w. SAs 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.# L% ?+ Y& k% c) r6 E
However, VCO related noise causes the bandwidth cannot choosed to too high bandwidth.
+ U- K" X( ^0 d+ Z- l6 gSo, linear model is usually useful. |
