Hi Friends,
I am trying to do the stability analysis on the Cadence tool and though I know well all the other analysis well, this analysis is confusing me a lot as I am trying it first time.
I am trying to simulate the loop gain of a non-inverting amplifier and somehow strangely it gives very absurd results with -150 dB loop gain.
One doubt I got is whether I have to connect to iprobe or vsource for loop gain calculation?? The result is with same absurd negative gain value with both.
I need to connect vsource as voltage source or I need to place it in series with the loop if I am going to use it??
I hope there are many people use it in this group and help me out of this problem.

Seems like some library components problem in the process I am using. It worked for me with a different process.
