A Novel DCVS Tree Reduction Algorithm

Abstract

This paper presents a new method to simplify the implemented functions by differential cascode voltage switch (DCVS) tree using a new levels coupling rule. The rule introduced in the context provides more reduction possibility by changing the designer's point of view. The proposed algorithm introduces a new approach for DCVS tree network design by making use of this rule and its combination with the former rules. This algorithm exploits ordered binary decision diagram (OBDD) structures to realize DCVS trees. The approach presented, remarkably improves speed and circuit area
