Single-supply, second-order, multiple feedback high-pass filter circuit




The multiple-feedback (MFB) high-pass (HP) filter is a 2nd-order active filter. Vref provides a DC offset to accommodate for single-supply applications. This HP filter inverts the signal (Gain = –1 V/V) for frequencies in the pass band. An MFB filter is preferable when the gain is high or when the Q-factor is large (for example, 3 or greater)
  • Single 5-V supply
  • Input: +/-2.45 V
  • Output: 50 mV to 4.95 V
  • Cutoff frequency: 1 kHz
  • Gain: -1 V/V
