Binary Coded Decimal (BCD) Seven Segment Circuit Designing using Quantum-dot Cellular Automata (QCA)

QCA is an alternative nanotechnology which keeps scaling down the technology further. It can do scaling beyond to a level where complementary metal oxide semiconductor (CMOS) scaling rises the issue. QCA is seen as an emerging solution for nano-architectures. This nanotechnology uses different logic devices for digital circuit designing for obtaining a high rate of performance at output. This new nanotechnology uses a specific method to represent and decode the data. The main aim behind our work is to understand the basic QCA technology and to get familiar with the QCA designer 2.03 software for getting involved in advanced designing of digital circuits using QCA. In our work, Seven Segment Display is proposed using different gates and majority voters in QCA. A seven Segment Display uses Light Emitting Diodes to display output that can be in the form of image, text or decimal number. The simulation results verify that our work is significant.
