Minimizing area and power is the more challenging task in modern VLSI design. Adders are the most widely used components in many circuits. The design of area and power efficient high-speed data path logic systems forms the largest areas of research in VLSI system design. Several types of adders are available in practice, each type is used for particular purpose based on their performance and features. In this project, design an efficient hybrid adder that combines the Ladner–Fischer adder with a ripple carry adder. And show that the hybrid adder has better performance (in terms of latency) in Quantum-dot cellular automata (QCA) than a Ladner–Fischer or a ripple carry adder. In proposed, design MAC (multiply accumulate) hybrid adder , the circuit is operational to perform a MAC (multiply accumulate) operation and to perform a multiply operation without interfacing with the accumulate value of MAC operation using Quantum-dot cellular automata (QCA). And Compare the area and power with existing adders.
