Inverting attenuator circuit



This circuit inverts the input signal, Vi, and applies a signal gain of –40 dB. The common-mode voltage of an inverting amplifier is equal to the voltage applied to the non-inverting input, which is ground in this design.
  • Input: Vi = -200 V to 200 V
  • Output: Vo = -2 V to 2 V
  • BW: f_p = 1 MHz
  • Gain; G = -40 dB
  • Supply:
    • Vcc = 2.5 V
    • Vee = -2.5 V
