In the schematic, the configuration A, inverting active band-pass filter, functions as expected with voltage gain at the resonant frequency of 5 kHz that approaches 10. This is from a book about op amps.
Configuration B is an attempt to do the same thing as A except in a non-inverting amplifier configuration so that voltage gain is never less than 1 (unity). For this config., voltage gain at 5 kHz is greater than 100.
Given that
(Ri + Rf) / Ri = 11
how is it possible for voltage gain of Config. B to be > 100?
