In the article, the Generalized Current Follower Transconductance Amplifier (GCFTA) element for generalized frequency filter design and a novel active element, the Programmable Current Amplifier (PCA) for the realization of the current-mode analog blocks, are presented. The paper also presents a method of general frequency filter design, whereas the basic circuit is a general autonomous circuit using GCFTA, PCA elements and general admittances. The properties of the proposed filter have been verified using PSPICE simulations.
