Algorithms for the sum of two (three and four) digits in the binary stored-carry number system, using the smallest set of values for the positional sum, are presented. The corresponding adders, which use multivalued current-mode circuits, are also presented. The implementation of multioperand additions using these adders is compared with the usual binary implementation. >
