Abstract
Among the emerging technologies in the nanotechnology domain, quantum-dot cellular automata (QCA) is an important name. It overcomes the serious technical limitations of CMOS. In this article, we have used two-dimensional 2-dot 1-electron QCA cells, a variant of two-dimensional 4-dot 2-electron QCA cells, to design a logically reversible half adder. Potential energies have been computed to substantiate and analyse the proposed design. The issues related to energy and power dissipation have also been discussed. Finally, our proposed architecture using 2-dot 1-electron QCA cells has been compared with the architecture using 4-dot 2-electron QCA cells.
