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~

 

Use one of the on-line polynomial root calculators capable of solving for complex results.

e.g

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

 

Thank you for your kind reply.... but I guess two of you didn't get it well....
What I actually need is to find the poles and zeros in terms of parameters... not values....
Thanks anyway!
