hello every one,
I have a basic Question regarding impact of spur on integrated rms jitter. When we multiply every individual block phase noise with respective transfer function and add all we get total pll phase noise curve, but we don't get spurs in this process but in the real time we get spurs at the reference frequency and those spurs add some thing to area, so while modeling how to consider this impact?

Thanks,
Raj.

hello loose electron,
thanks for your responce. I know that jitter and phase noise are related. Could you please tell me how to model reference spurs in the model? I would like to incase of a simple 2nd order loop filter pll.

Thanks,
raj.

hello loose-electron,
what is the use of estimating Control voltage FFT? i know it gives more or less phase noise scaled by Kvco am i correct?

Any how thanks i will try implement this.

Thanks,
raj.
