Quantum Dot Handheld Automatics is one of the best technologies in recent days for introducing a high speed and ultra-low powered digital circuit. Few binary and decimal arithmetic circuits were designed using an efficacious QCA-based algorithm. However, there is a substantial enhancement required yet if there is inbuilt availability of logic gates inside the QCA. Therefore, this article introduced innovative binary coded decimal (BCD) adders using QCA methodology. Simulation analysis discloses that proposed BCD adders obtained higher computational speed with lower delays and lesser area than conventional CMOS approaches.
