A new active network suitable for realizing ladder filters and transformer simulator

Abstract

A general configuration suitable for realizing low-pass and high-pass ladder filters and transformer simulator, depending on the passive element selection is proposed. The proposed network employs only grounded passive components without requiring matching conditions. The values of the synthetic inductances of the transformer and low-pass ladder filter can be changed independently. SPICE simulation results confirming the theoretical analysis are included. © World Scientific Publishing Company.
