Review on Low Power energy efficient VLSI circuits using Adiabatic logic

Sarada A, Dr.K.Ragini

The ever-growing number of transistors integrated on a chip and the increasing transistor switching speed in recent decades has enabled great performance improvement in computer systems by several orders of magnitude. Unfortunately, such phenomenal performance improvements have been accompanied by an increase in power and energy dissipation of the systems. Higher power and energy dissipation in high performance systems require more expensive packaging and cooling technologies, this in turn increase cost, and decrease system reliability. Demands for low power electronics have motivated researchers to explore new approaches to reduce power consumption and energy dissipation in VLSI circuits. The classical approaches of reducing power consumption, energy dissipation in conventional CMOS circuits included reducing the supply voltages, node capacitances, switching frequencies and recycling energy back to power supply respectively. In this paper a review about subthreshold operation, adiabatic logic and adiabatic logic in subthreshold region.
