  • Abstract
    An adequate model of a nonideal op-amp operating in a two-op-amp SC biquad is derived. The model leads to an equivalent SC circuit containing ideal components. Substitution of any op-amp in an SC biquad by its equivalent SC circuit allows the exact frequency response of the biquad to be found easily, taking into account the finite DC gain and bandwidth of op-amps.
