Sk. Mahammad Akram, V. Leela Rani, K. Sailaja . Implementation of Low Leakage and High Performance 8-Bit ALU for Low Power Digital Circuits. International Journal of Computer Applications. 82, 18 ( November 2013), 24-28. DOI=10.5120/14265-2411
The insist for portable devices is fulfilled by the growing CMOS technology. As the size of the transistor shrinks, the leakage power component augments exponentially. Thus it becomes a critical metric for the future technologies. This paper deals with the techniques like GATED VDD, AVLS, AVLG, and AVL for reducing leakage power. These techniques are implemented on 8-bit ALU. 80% of cutback in leakage power can be achieved by applying proposed technique with minimum delay and area overhead. The circuit is simulated on cadence(R) Virtuoso(R) in 90 nanometer CMOS technology.
