I am simulating a CSA-Comp pair like in the picture below (Picture 1) and would like to use PSS and PNoise analyses to find the input-referred noise charge or equivalent noise charge (ENC).
But I got no noise result in the data browser and warning message "WARNING (SPCRTRF-15495): No crossing events detected for jitter measurement pm0. " pops up in the simulation log.
The analysis setup from here is my reference. Picture 2.
The comparator in my circuit is the asynchronous one and that paper says that the same method can be used.
The Spectre expression of my simulation is shown in Picture 3.
I have never used periodic analyses (pss, pnoise, ect).
Maybe someone can suggest me things to check?
