A Literature Review on Leakage and Power Reduction Techniques in CMOS VLSI Design

A rapid growth in semiconductor technology and increasing demand for portable devices powered up by battery has led the manufacturers to scale down the feature size, resulting reduced threshold voltage and thereby enabling integration of extremely complex functionality on a single chip. In CMOS circuits, increased sub-threshold leakage current refers static power dissipation is the result of low threshold voltage. For the most recent CMOS technologies static power dissipation i.e. leakage power dissipation has become a challenging area for VLSI chip designers. According to ITRS (International technology road-map for semiconductors), leakage power is becoming a dominant part of total power consumption. To prolong the battery life of portable devices, leakage power reduction is the primary goal. The main objective of this paper is to present the analysis of leakage components, comprehensive study & analysis of leakage components and to present different proposed leakage power reduction techniques.

Optimized Reversible Logic Multiplexer Designs for Energy-Efficient Nanoscale Computing

Nano- and quantum-based low-power applications are where reversible logic really shines. By using digitally equivalent circuits with reversible logic gates, energy savings may be achieved. Reducing garbage output and ancilla inputs is a primary emphasis of this study, which aims to lower power consumption in reversible multiplexers. Multiplexers with switchable 2:1, 4:1, and 8:1 ratios may be built using the SJ gate and other simple reversible logic gates. The number of ancilla inputs has been cut in half from four to zero, and the amount of garbage output has been cut in half as well, from eight to three, making the 2:1 multiplexer an improvement over the prior design. New 4:1 multiplexer has 10' ancilla inputs, up from 2' in the previous designs. The proposed 4:1 multiplexer also cuts waste production in half from the current 5-to-6 bins per day. The 8:1 multiplexer has two ancilla inputs and nine trash outputs, while the current architecture only has one of each. The functionality of the VHDL and Xilinx 14.7-coded designs is validated by ISIM simulations

Intelligent Robotics: Navigation, Planning, and Human-Robot Interaction

The development of robotic systems that are able to independently navigate their environments, effectively plan their activities, and communicate naturally with people has given rise to the field of research known as intelligent robotics. The objective of this abstract is to give a summary of the developments in intelligent robotics with regard to planning, navigation, and human-robot interaction. As a result, the fields of navigation, planning, and human-robot interaction have seen notable breakthroughs in intelligent robots. Robots are now capable of navigating across complicated areas with efficiency because to the development of reliable navigation algorithms. Robots may now use planning strategies to make wise judgments and carry out activities on their own. Additionally, research on human-robot interaction has concentrated on creating user-friendly interfaces that allow for seamless collaboration between humans and robots. These developments open the way for intelligent robots to become fundamental elements of our society, improving output, security, and quality of life across a range of fields. But more study is still needed to address issues like long-term autonomy, environment adaptation, and the moral ramifications of widespread use of intelligent robots
