Hello all,

I am simulating a complex amplifier architecture, and I am interested in monitoring the pole zero locations using PoleZero analysis. I have a couple of questions w.r.t. Spectre analysis:

1. The dominant pole shown by AC, is missing in Pole Zero analysis. This is slightly strange because other high frequency poles are correctly reported

2. Is there any improvement in PZ analysis in various Spectre versions ? lets say from IC 5.1.41 to IC 6.14/6.15 ?

Looking forward for good answers.

CHeers !
