Abstract

In nano scale logic computing, dissipated heat and device area are the key areas of interest. Ideally zero heat dissipation can be achieved in reversible circuits by preserving information. This paper presents an original method and a practical design implementation of carry look ahead Adder.Among several nano-devices, QCA has elevated functionality in designing circuits at nano scale. A circuit for carry look ahead generator and its realization in QCA has been reported in this paper. To achieve the proposed design, majority gate based AND operation and OR operations have been used to design an EX-OR.These designs are verified and compared with a ripple carry adder. This comparison establishes the computing accuracy of the proposed designs. The design can function as a heart for faster parallel adder at nano scale level.
