Hi all,
I am trying to run PSS + sampled PAC on a sample and hold, and I have noticed two problems.
1) I used the "sampled PAC" analysis directly in spectreRF, and it allows me to plot the PAC waveforms for specific time instances. However, when I try to do a parametric sweep of a DC bias (for example), I can no longer plot the waveform at a specific time instance, and the waveform is always averaged over time. How can I get around this?
2) One solution I tried for the above was to use normal (not sampled) PAC analysis, and then add an ideal sample and hold at those nodes I want to analyze (sah_ideal from analogLib). However, when I do this, the PAC node voltage is attenuated by about 80 dB. Does anybody know the reason for this?
thanks, Aaron
