Hi Frank, to make sure I do it correctly, can I formulate it as follows? After 'sampled pxf' analysis, I got two tranfer function plot with respect to the Vdd and Vss. So, suppose I know that the power noise or substrate noise is characterized by a sinwave of 1mV and 1MHz, then I find the resulting noise at the output by mulitiplying 1mv with the gain at 1MHz. Finally, I divide the resulting noise by the slope, which gives me the jitter. Is that right? If it is, I was wondering what if the power or substrate noise is not well approximated as a sinwave, but with a certain spectrum, for example 100k to 1MHz, because in reality the power noise is very complicated? Thanks very very much.
