Abstract: Ultra low power CMOS digital integrated circuits are the enabling technology for the modern portable and bio-inspired systems. The efficiency of these systems has been realized with requirement of low power for their operation. As for the fulfillment of the requirement of present technological world, we are on the way to commercialize these devices to the nano scale. Higher functionally and higher performance of digital circuits are required at lower power consumption. So with the increasing need of ultra-low-power digital circuits, study of less power VLSI design has grown one of the most essential influences in continuous development of nano electronics. This survey focuses on the various considerations in ultra low power CMOS VLSI designs for broad class of portable and bio-inspired system architectures. Consideration of remedies of large power benefits in low power consumption by digital devices even below 45 nm technologies. However, in spite of their importance in advancement of ultra low power digital VLSI design for recent technology, these power reduction methods and their comparisons have never been surveyed so far. The essential aim of this paper is to fill the existing gap by addressing an extensive review of sources of power dissipation, power approximation and optimization techniques at different level of design abstraction layers, various technologies for ultra-lowpower design and their implementation in bio-inspired systems. A tabular representation of various power reduction methods and comparison of different power reduction techniques has been presented. This paper goes through the detailed review of energy recovery logic called adiabatic logic for ultra-low-power design by discussing various fully and partially adiabatic logic styles. After presenting the above low power technologies this paper discusses the potential of these technologies in emerging trends of bio-inspired systems. � 2017 by American Scientific Publishers.
