The circuit of the high gain band-pass filter with low Q is shown in this figure. Adding multiple feedback circuit to operational amplifier can build up a high gain band-pass active filter with low Q. This circuit adopts LM307 operational amplifier, using the components’ parameters in this figure to calculate: BW is the bandwidth when the gain of the operational amplifier is 1.
