I´d like to do a pz simulation of a circuit to see the pole movement under different operating conditions.
To do so I did a stb analysis first.
Then I compared the location of the poles from stb analysis to the ones gotten by the pz analysis.
And unfortunatelly they are totally different.
What could be the reason for this?
I assume that the operating conditons are the same.
Oh I forgot. I´m using Cadence 6.1.5
