Implementation of Full Adder Cell Using High Performance CMOS Technology

This paper proposed design and implementation of full adder cell which is efficient in terms of both speed and energy consumption which becomes even more significant as the world length of the adder increases. We are introducing adders for low power imprecise applications. In this we propose a full adder design having low complexity, higher computing speed, lower energy consumption, and lower operating voltage. We will explain how to realize a general full adder circuit based on transistor using CMOS technology. The performance of the proposed full adder is evaluated by the comparison of the simulation result. In this system, not signals are generated internally that control the selection of the output multiplexers. Instead, the input signal, exhibiting a full voltage swing and no extra delay, is used to drive the multiplexers, reducing the overall propagation delays. The capacitive load for the input has been reduced, as it is connected only to some transistor gates and some drain or source terminals. The design a full adder having low complexity, higher computing speed, lower energy consumption, and lower operating voltage. Full Adder models to make it understandable for designer. We are giving high throughput with less complex system by showing synthesizable and simulated results.
