Design And Power Optimization of ALU Using Adiabatic Logic

This study delves into the integration of adiabatic logic into ALU design, aiming to boost energy efficiency without compromising performance. Traditional ALUs employing CMOS technology often exhibit substantial power consumption due to transistor count. We compare a conventional CMOS-based ALU, consuming 56. 68 x 10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-6</sup> units of power, with an adiabatic logic-based ALU, which consumes only 4.076 x 10-9 units of power, illustrating a significant reduction. Adiabatic logic operates on the principle of energy recovery, recycling consumed energy back into the power supply to mitigate overall power consumption. Our study looks at different adiabatic logic designs and how well they work to minimize power loss without sacrificing functionality and gives a remarkable reduction in the power. The results show that adiabatic logic can be used to create ALU designs that are energy-efficient, which makes it an interesting area for low- power VLSI circuit research which helps in the designing of a high computing systems. With low-power solutions becoming increasingly necessary in contemporary VLSI circuits, this research advances our understanding of how well adiabatic logic can improve energy efficiency in ALU designs.
