[SI-LIST] Re: bandpass

Why do you need to do this in op-amps?  You can use any old FM filter off 
the shelf.  If you use an op-amp for a BP filter, you need lots of spare 
GBW product.  The only thing that is going to get you close will be a 
current mode device.  If you must go that route, go look at Elantec.
