Mathametical Modelling of Full Adder using Carbon Nanorods

Abstract

Nanomechanical computational systems proposed by K.Drexler is one of the approaches to molecular scale electronic circuits for memory and logic applications. The nanomechanical rod logic proposed is distinguished by its small size and very low energy dissipation, compared to transistors. it has been found from the sources available to us, that presently the idea was highly unexplored and still remains in its nascent stages This paper presents the use of nanorods as variant to the existing silicon technology for the design of a full adder circuit along with the speed, power and energy dissipation characteristics. The full adder circuit is then extended to an n-bit adder (which forms the basis of an ALU circuit). The paper also addresses the use of parallel architectures to overcome the limitations of switching speeds.
