Abstract
The general two-graph framework for designing series and parallel R-L imittances is presented. The transformation of passive LC-filters into active RC-circuits using signal-flow graphs in the two-graph version, is the basis of this method. The idea consists of using exclusively RC-elements and the newly introduced ’active switches’. A second novel idea is presented; it consists of the reduction of the complexity of the equivalent active circuits, i.e. reducing the number of active elements to reproduce the ’same’ circuit’s behavior, but at the cost of a reduction of the quality factor. SPICE simulation results are presented to show the viability of the proposed approaches.
