pfd-cp mismatch
If my simulation includes only PFD, CP and the loop filter components, what simulations do I have to run to make sure my PFD/CP is working ok? I've run phase sweep between 2 identical frequencies going into the PFD, and plotted average integrated CP output current vs. phase difference to check to dead zone. Assuming the DC analysis for CP current mismatch over voltage variation and temp is already taken care of, what other simulations do I have to run for the combination of PFD/CP? Appreciate the comments!
