WebIn selecting an amplifier for building the biquad filter, the rule of thumb is that it is recommended to have a minimum of 20 dB of loop gain at the center frequency, looking at the band-pass output. In the biquad filter, the amplifiers are used as an integrator (in the low-pass in-phase output), which sets the bandwidth requirement.
