How do I check the stability of Multiple pole feedback Bandpass filter?
Short answer
That circuit was generated by ADI's filter design wizard, and that shows the amplitude response, right? Does that look unstable to you?
Longer answer
Point is that you can of course set up an equation system using the model of an ideal opamp, derive the positions of the poles, then do the usual &quot;region of convergence includes unit circle&quot; etc tricks.
However, this isn't an ideal opamp, so that equation system will get ugly very quickly, not be linear at all, dampened in ways that your ideal opamp can't represent, and be solvable only by a computer, anyway. So, use the simulation model of the opamp to begin with. The tool you're already using does that, but you might as well use SPICE and other circuit simulators.
