Synthesis and Applied of High-Efficiency Balanced 2nd Active Filters Using a Generalized Cross-Over Architecture

Abstract

This paper proposes a novel methodology for the synthesis and practical realization of high-efficiency active filters. The approach is based on a generalized architectural framework that incorporates integrated cross-over feedback paths, enabling the development of active filter circuits with a substantially reduced number of passive and active components compared with conventional topologies. Unlike classical filter transformation techniques that are often associated with component redundancy and increased structural complexity, the proposed cross-over architecture provides a more efficient mathematical mapping of transfer functions onto physical circuit implementations. The resulting designs preserve key performance characteristics, including straightforward tuning procedures and low sensitivity to component tolerances and environmental variations. Consequently, the proposed methodology offers a streamlined and robust design strategy for achieving high-precision active filters without the overhead typically associated with component-intensive filter realizations
