Hello Frank,
Thank you. It seems the sampled PXF gives the sensitivity of the output jitter to the supply ripple, and it is a smallsignal condition. Since the result from PXF divided by the slope dv/dt has the unit sec/V, how to calculate the jitter at the output due to the power supply ripple? Also is the PXF giving the transfer function in Frequency domain? If so, it should be a frequency dependent transfer function (at least plot from 0 Hz to f0, f0 is the beating frequency)? how to choose the value from the PXF result? Assume we already know the sensitivity for the output jitter to supply ripple, but the ripple on the power supply is an unknown value, how to calculate the jitter? I am guessing if I need to average the ripple value, and use the averaged ripple voltage multiply the sensitivity to get the "RMS jitter". Please give me a hint, and I hope I will not bother you on this problem again. Thank you. Have a nice weekend.
