Comparative Analysis of Energy-Efficient Low Power 1-Bit Full Adders at 120nm Technology
In this paper, the authors present new Low power and Energy efficient 1-Bit Full adder designs featuring Centralized, XOR-XOR and XNOR-XNOR CMOS design styles. Energy efficiency is one of the most required features of the modern electronic System designed for high performance and Portable applications. They carried out a Comparison between these designs reported as having a low PDP, in terms of Speed, Power consumption and Area. The proposed full adders are energy efficient and outperform several standard Full adders without trading of driving capabilities and reliabilities. The new Full adders successfully operate at low voltage with excellent Signal integrity and Driving Capability.
