    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.

    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!
