Abstract | The popularity and explosive growth of portable electronics motivate the designers to drive towards system designs with a smaller silicon area higher speeds and higher reliability Last decade onwards the emphasis of the system design in VLSI has shifted from high speed to low power However electronic portable devices such as Personal Digital Assistants notebook computers and mobile phones require enormous volume of data processing to be done For such multimedia devices the prime goal of using low power design is to curtail the total power dissipation of the system to preserve the reliability of the integrated circuit chips The main sources of power dissipation are dynamic and static power dissipation In deep sub-micron circuits leakage power in static power dissipation has become an increased proportion compared to dynamic power dissipation For CMOS technologies below 65nm 50 percentage of total power consumption arises from leakage current During the last few years various low power design techniques have been implemented to reduce leakage power at multiple abstraction levels There are various types of leakage current out of which sub-threshold leakage current is predominant in deep sub-micron devices Initially a search was done on circuit level design methods to reduce the active mode or static mode of power dissipation This search revealed the achievement of reduction in static power dissipation at the expense of active power dissipation However both types of power dissipation require reduction in order to have reduced total power dissipation in deep sub-micron designs |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
