Advanced Low-Power Design Techniques in VLSI Circuits

Abstract

Low-power VLSI design has become a crucial area of research due to the growing demand for energy-efficient and high-performance integrated circuits. As technology scales down to nanometer levels, power dissipation emerges as a significant challenge affecting device reliability and lifespan. This paper explores various low-power design methodologies, including dynamic voltage scaling, clock gating, power gating, and multi-threshold CMOS techniques. The study also investigates the impact of transistor sizing, leakage current reduction, and advanced fabrication technologies on minimizing power consumption. Simulation results from various low-power design approaches demonstrate a significant improvement in power efficiency while maintaining computational performance. The findings contribute to the development of future energy-efficient VLSI architectures, essential for battery-powered devices and large-scale data processing systems.
