Synthesis of arbitrary rational transfer functions in s using uniform distributed RC active circuits
John M. Khoury, Y. Tsividis · IEEE Transactions on Circuits and Systems · 1990
A synthesis technique is described whereby network functions that are rational in s are realized with uniform distributed RC elements and active elements. 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 Chebyshev, and well-known filter topologies can be used. Experimental results for a band-pass biquad are presented, and practical implementation possibilities are discussed.>
