Dear antia66,
) j2 c7 \7 w& _8 f' SIf damping factor is choosen 2, how about the natural freqency?# p! l) ]& q& _$ \" T0 W# o9 Z
Will the natural freqency changed with damping factor ?
4 M+ A, u& E5 {( ^6 C6 ~, j( QAs 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# E$ m3 B) ~; z) g7 yHowever, VCO related noise causes the bandwidth cannot choosed to too high bandwidth." U; k+ K0 O7 ^1 i
So, linear model is usually useful. |
