nu MOS-based sorter for arithmetic applications

Abstract

The capabilities of the conceptual link between threshold gates and sorting networks are explored by implementing some arithmetic demonstrators. In particular, both an (8×8)-multiplier and a (15,4) counter which use a sorter as the main building block have been implemented. Traditional disadvantages of binary sorters such as their hardware intensive nature are avoided by using νMOS circuits. It allows both an improving of previous results for multipliers based on a similar architecture, and to obtain a new type of counter which shows a reduced delay when compared to a conventional implementation.
