Abstract
Quantum-dot Cellular Automata i.e. QCA is emerged as a product of immense study made by researchers to find out an efficient replacement of CMOS technology in nanoscale. Nanoscale alternatives arise due to the fact that CMOS is near to face serious challenges due to the scaling limitation of this technology. The nanoscale implementation of CMOS also suffers from high power dissipation. In this present article, a study has been carried out over the structural advantages of square shaped 2Dot 1Electron QCA cells over the rectangular shaped cell. As an case study, a design strategy of a half subtractor as well as a full subtractor has been proposed using 2Dot 1Electron QCA and an analysis has been carried out with respect to the cell structure. The design of the half subtractor consists of only 25 many number of 2Dot 1Electron QCA cells. On the other hand, the full subtractor design contains 40 many number of cells. Using this design approach, we have achieved upto 67% and 65% of efficiency with respect to the cell count over the existing half and full subtractor implementation using 4-dot 2 electron QCA respectively. No such study has been carried out in this domain till date.
