Design of Decimal to BCD Code Converter using Reversible logic and QCA

In the field of Quantum computation, the reversible logic and nanotechnology has gathered a lot of attention of researcher’s in the recent years due to its low power dissipation quality. Quantum computing has been a guiding light for Bio-informatics, Nanotechnology, optical information computing, low power CMOS design, DNA computing and low power VLSI. In digital system, Code converters are considered to be very essential component and are needed day in and out. Generally, the encoders are utilized in converting a 2n bit number to n bit number. In this paper, an optimized design of Decimal to BCD code converter using a new proposed reversible gate i.e. FR gate is proposed. The proposed design offers an improvement of 26.67% and 54% over the existing design in terms of its garbage outputs & Quantum cost respectively. The Proposed gate and Decimal to BCD converter are finally designed & successfully tested using the simulations obtained from QCA designer.
