Original Abstract

This paper investigates the influence of the current operational amplifier real properties on the current-mode multiple feedback low-pass filter. The amplifier is modeled by a one-pole model with non-zero input impedance. The symbolic relations for shifted poles and zeros of the filter are derived and the concrete impacts of the modeled amplifier properties on the filter frequency characteristic are determined. The recommended relations between amplifier and filter parameters are provided.
