Synthesis of Arbitrary Rational Transfer Functions in S Using Uniform Distributed RC Active Circuits

This paper describes a synthesis technique whereby network functions that are rational in s are realized with uniform distributed RC elements and active circuits. In contrast to previous distributed synthesis approaches, the technique works directly in the s plane without complex mathematical transformations, uses only grounded rectangular single-layer uniform distributed RC structures, and can realize many network topologies. Classical approximation functions, such as Butterworth and Chebychev, and well-known filter topologies can be used. The technique is applicable to thin-film hybrid circuits, MOS integrated circuits and other technologies. A synthesis example is presented.
