active filter simulation

Hello all,

I want to design Active filters(using Op-amps),Can anybody upload some papers or tutorilas for the same either in Ansoft desinger or in Microwave office?

Why do you restrict yourself to these two software packages ?
For designing active filters with opamps there are several powerful programs available - some for free ! Are you interested ?

Well. here are some useful links:

- Filter Free: www.filter-solutions.com

Hello sekharareddy,
