Foundational elements and functional analysis of multi-valued logic

Abstract

The author discusses the advantages and drawbacks of two logical implementations: voltage-based radix-2 logic (VBL) and current-mode redundant radix-2 logic (CML). He then explores the basic elements of a CML implementation and discusses application options and optimizations. The advantages inherent to this type of implementation are portrayed in data storage, arithmetic combinations and, to a limited extent, information routing. The feasibility of utilizing this technology was proven through SPICE simulations of each cell. The performance of individual units, even under loaded conditions, is sufficient. However, extensive SPICE simulations may be required for creating combinatorial cells. Consequently, it is concluded that further work needs to be investigated into the expansion of the present knowledge of current-mode mult-values logic.<>
