In order to measure the AC gain, u need to give dc at both input and AC=1 at one of the positive or negative input. Then, measure the gain by clicking VF at calculater, click at the both output node, then click at both input node and model the formula in calculation and plot. then you will get the ac gain.
Pipeline,
PSS is a frequency based analisys. It is used for swithched capacitor circuit and mixers. Using this analisys it is possible to know the gain corresponding to different input frequency taking in consideration frequency translation effect.
You can find more details in the manuals and tutorials.
Also some details on Ken Kundert (Cadence author) site: https://www.designers-guide.org/Analysis/
Hope it helps
below; i attached tutorials to explain how to use many analysis in the spectre,,including PSS,PAC....simulating the phase noise....etc...hope that help you
