Energy Efficient Design of Full Adder using theXOR/XNOR Gates

Since the past decade, the semiconductor industry has seen an explosion in advanced interactive applications integrated with electrical gadgetry. The most frequently and extensively utilised circuits in (Integrated circuit) systems are fast arithmetic calculation cells, which include adders and multipliers. XOR-XNOR circuits are fundamental building elements in a wide variety of circuits. Because of their low yield capabilities and low power consumption, the latest new FA modules are more efficient in terms of Area and the power. This article proposes a low-power full adder utilising an efficient logical method, which lowers power consumption by constructing a full adder using the EXOR-EXNOR circuit. The full-swing EXOR–EXNOR or EXOR/EXNOR gates are used in these proposed circuits. Each of the new designs has its own preferences in terms of speed, energy consumption, delay product, driving capacity, and time. Tanner/Xilinx ISE simulation tools are used to test the execution of the new structures.
