An algebra for current-mode CMOS multivalued circuits

Based on the transmission function theory for voltage-mode CMOS circuits, an algebra for current-mode CMOS multivalued circuits is proposed. In this algebra, the switching state of MOS transistor and the current signal are represented by two kinds of variables, respectively. Some operations are introduced, their properties are discussed, and the synthesis of current-mode CMOS multivalued circuits by algebraic means is presented. A design example shows that this theory not only can explain current-mode CMOS multivalued circuits proposed previously, but also develops new designs with simpler construction
