Original Abstract

The paper describes a novel structure of the universal multifunction filter working in the pure current mode. Due to better frequency features of the current mode and a tendency to reduce the supply voltage because of the technology used (where in the voltage mode the dynamic range goes down in the voltage domain), we decided to design a universal filter working in exactly the pure current mode. It is a circuit where the active elements are only the current-controlled current sources. The current buffer with one input and one positive and one negative output appears to be the optimum element. The bipolar structure of such a current buffer is designed and the basic simulations are carried out.
