I run pz analysis in spectre for 2stage amp connected as buffer and got the pz results listed below which is very small. I expect M level values for pole zero values. Poles (Hz) Real Imaginary Qfactor 1 -2.70560e-06 +/- 1.53583e-04 2.83869e+01 2 -1.69713e+01 0.00000e+00 5.00000e-01
For the pz sim, I use default options. Could you tell me the possible reasons for the strange results?
Thank you!
