In this paper, a procedure for direct form realization of Active-RC all-pole filters is presented. The filters are based on the resistance-capacitance ladder structure combined with the single operational amplifier and multiple feedback for complex pole realization. Recursive formulas have been developed that determine transfer function coefficients and derivation of transfer function coefficient with respect to filter components. These design equations are developed without knowing filter coefficients in terms of filter components in closed form, and they are necessary and sufficient for the filter design. Performance of these filters base been compared with the classical cascade form realization.
