# Finding Poles and Zeros Location from Transfer Function

Hi everyone!

I am doing project on Analog, and now trying to get the pole and zeros location from my transfer function.
However, since I think I have a complex conjugate pole pair at frequency higher than UGF, I cannot use coefficient dividing method to get the approximated pole locations.

Anybody can share on how to get the pole locations?

I have attached my transfer function in this post...
I am really looking forward to your kind help~
Thank you so much~

Try to find out the roots of Vin & plot those roots on complex plane. Then u will get pole of ur Tr function.
