Calculate noise in active filters?

How do I calculate output noise in active OP amp filters?



I would like to calculate the theoretical output noise of my active bandpass filter.



Could I use Switcher CAD III from Linear Technology to simulate noise?



Yep. Unfortunately the noise model of the OpAmp may NOT be properly characterized.
