Abstract | A new video-speed, current-mode, CMOS, sample-and-hold circuit has been developed. It operates with a supply voltage as low as 1.5 V and a signal-to-noise ratio (S/N) of 57 dB and 54 dB at clock frequencies of 20 MHz and 30 MHz. It consists of current mirror circuits with an analog switch and a capacitor placed in differential form to achieve high accuracy without being affected by the switch feed-through error. Voltages at the input and the output terminals of the current mirror circuit are kept constant to obtain precise current matching. The circuit was fabricated using 0.6 µm MOS devices with normal threshold voltages (Vth) of +07 V (NMOS) and -0.7 V (PMOS). |

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.
