I have two high-q band-pass filters with TI op-amp OPA2376 (http://www.ti.com/product/opa2376) in series of each other. Here is one of them:
My objective is to center the band-pass around 40kHz. On the input, I have some strong noise around 15kHz. Therefore, I want to have a good gain slope that filters such noise (everything below 25kHz is really cut-off) and still gains a lot my signal (everything above 35kHz is gained up).
On the other (upper) side of the band-pass, I have more flexibility. I know that the two stop points are not equally spaced above and below the center frequency but they will look equally spaced if plotted on a log graph. Once again, the upper band is about to be safe so the cut-out frequency can be higher if needed.
What values would you recommend?
