ABSTRACT
The Integrated Circuit Technology (IC) is growing day to day to improve circuit performance and density for compact systems. A novel technology, Quantum dot Cellular Automata (QCA) was introduced to overcome the scaling limitations of CMOS technology. In order to bring a new paradigm of IC design in an efficient and optimized manner, a binary to BCD code converter is designed using QCA technology based area optimized adder. It is observed that the proposed binary to BCD code converter design gives better results in terms of the area and number of QCA cells. The results obtained by the proposed design shows that 61% of area reduced compared to boolean expression based design, this design is further optimized to reduce the QCA cell count by 45% with respect to the design in [1].
