Abstract

There has been considerable research on quantum dotcellular automata (QCA) as a new computing schemein the nano-scale regimes. The basic logic element ofthis technology is majority voter. In this paper, a detailedsimulation-based characterization of QCA defectsand study of their effects at logic-level are presented.Testing of these devices is investigated and compared withconventional CMOS-based designs. Unique testing featuresof designs based on this technology are presented andinteresting properties have been identified.
