An enhanced design of BCD adder using quantum-dot cellular automata technology

Abstract

Among the promising advancements proposed as options in contrast to the CMOS, Quantum-dot cellular automata (QCA) is a standout amongst the mainly encouraging answers for design ultra-low-control and rapid digital circuits. Productive QCA-based executions have been exhibited for a few binary and decimal math circuits, yet noteworthy enhancements are as yet conceivable if the logic doors inalienably accessible inside the QCA innovation are astutely misused. The Quantum dot cellular automata are utilized to execute the digital circuits. The QCA inverter and QCA larger part entryway are utilized to manufacture the more mind boggling logic circuits. The QCA designer instrument is utilized for designing and recreating the format of the circuit. The most encouraging answer for design low power and rapid digital circuits. Productive QCA based usage have been exhibited for a few binary and number juggling circuits. This brief proposes another way to deal with design QCA based BCD adders.
