| Abstract | A 10-bit 30-Msample/s pipelined analog-to-digital converter is designed and implemented in a 0.6mum CMOS technology. Sampling capacitors scaling technique is employed to reduce the power dissipation. The digital correction technique is used to relax the offset requirement of the comparators. A sample-and-hold amplifier (SHA) is also used to improve the signal-to-noise and distortion ratio (SNDR) performance and the linearity of ADC. The simulation and experiment results reveal that the ADC designed with this method achieves the SNDR of 58dB or the ENOB of 9.34 at full speed of 30MHz when input frequency is 7MHz. Furthermore, the ADC consumes only 50mW power at 5V supply voltage with a low power operational transconductance amplifier (OTA) and the dynamic comparators |

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.
