with respect to what?the open-loop gain decreased and open-loop BW increased and GBW remain constant
this analysis and simulation for stb analysis in cadenceHi,
with respect to what?

I have a problem in this circuit when I simulate its loop gain on cadence
the open-loop gain decreased and open-loop BW increased and GBW remain constant
How is that a problem?I have a problem in this circuit when I simulate its loop gain on cadence

How did you simulate the loop gain? Did you take care of the correct bias points?i expect the LG= Aol(first stage)*Aol(second stage), and BW limited to OTA BW.
when i simulate i found that LG= Aol(first stage only) and BW= BWota *(Aol second stage "common source).
