Two techniques for designing a class of low-sensitivity, follow-the-leader, feedback-type active filters have been introduced by Hurtig and Laker-Ghausi. The FLF configuration consists of a cascade of second-and/or first-order sections, with feedback from each section back to the first. This paper presents an approach for designing FLF-type realization for all classes of filter functions. The technique is based on a shifted-companion form of the associated-state equations. Some salient features… CONTINUE READING
