Multiple feedback band-pass filter circuit




This circuit is a 2nd-order multiple feedback (MFB) band-pass (BP) filter. This BP filter is created by cascading a low-pass and a high-pass filter. Vref provides a DC offset to accommodate for single-supply applications.
  • Input: Vi = -2.45 V to 2.45 V
  • Output: Vo = 0.05 V to 4.95 V
  • Supply:
    • Vcc = 5 V
    • Vee = 0 V
  • Gain: 1 V/V
  • Low cutoff frequency: 1 kHz
  • High cutoff frequency: 10 kHz
  • Vref = 1.25 V and 2.5 V
