SPICE modeling and analysis for metal island ternary QCA logic device

Abstract

The exploration of work ability of the new trend in quantum dot cellular automata (QCA)—the ternary QCA, is the major focus in this paper. Both physically and electrically, our tQCA approach is proving its excellence in comparison to the existing binary QCA (bQCA). We also propose a model description for tQCA that will help in determining its logic performances while operating it in the nano computing regime.
