The Quantum Dot Cellular Automata (QCA) is a latest technology that has gained the curiosity of researchers due to its small size and low power consumption, so it is being researched as a suitable alternate to the CMOS technology. The QCA technology provides a new computational platform in designing digital circuits with the help of quantum-dots. Quantum dots have wide range of application like LED, medical imaging and quantum computing etc. The quantum-dots are Nano crystals that transfer information at Nano scale. This paper proposed an area efficient design and implementation of a 16-bit Multiply-Accumulate unit (MAC). It�s been designed by designing an area efficient novel 1-bit Full adder using QCA it is further used in a 16-bit Parallel binary adder and 8-bit multiplier modules. The design put forth for proposed 1-bit adder has brought down the cell count by 9.09% and area by 33.33%.The proposed design of multiplier has decreased the cell count by 18.7% and area by 9.92% in contrast to other previous designs. The proposed design of MAC has 27110 cells and its area is 77.89 ?m2. The simulation results have been verified using the QCADesigner Simulation tool. � 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
