It overcomes the serious technical limitations of CMOS at the nano level In this article, we have used two-dimensional two-dot one-electron QCA cells to design a binary to BCD converter. We have justified our proposed design by determining the polarity of different cells including output cells using coulomb law to justify its effectiveness. Finally, we have discussed the issues related to energy and power dissipation in order to drive the proposed architecture. c  2015 The Authors. Published by Elsevier B.V.

Introduction The technology of quantum-dot cellular automata (QCA), proposed by Lent and Tougaw 1 , is becoming one of the emerging technologies of the future computers because of its extremely small feature sizes, ultra low power consumption, simple conceptualization. It also does away with state off leakage current, dimensional restrictions and degraded switching performance, which are the inherent drawbacks of the CMOS technology. The advantage of 2-dot 1-electron QCA is that the number of dots and the number of electrons per cell is half of that in case of 4-dot 2-electron QCA. Moreover, it eliminates the four ambiguous configurations out of the six possible configurations 2 . Also, as binary information passes from cell to cell using the inter-cellular interaction obeying the Coulomb’s principle, the complexity of wiring is reduced. * Tel.: +91-943-411-3468 E-mail :kakali.datta@visva-bharati.ac.in ** Tel.: +91-974-807-7338 E-mail :debarka.mukhopadhyay@gmail.com Tel.: +91-943-315-5116 E-mail :paramartha.dutta@gmail.com © 2015 Published by Elsevier B.V.
