Strobed noise analysis
Hi to all,
I want to specify the edge-to-edge jitter of a frequency divider.
I have read the paper of Ken Kundert "Predicting the Phase noise and jitter of PLL - based synthesizers" (can be found at www.designers-guide.org ) which suggests the use of pnoise analysis in SpectreRF and specifically the timedomain noise feature (also known as strobed noise analysis)
However I cannot understand how to use this feature. I have to fill one of the fields "Noise Skip Count" or "Number of Points" but I cannot understand their meaning nor the manual is clear.
If someone has used this feature I would appreciate any help.
Thanks!
