| Abstract | A reconfigurable and simultaneous dual band Galileo/GPS front-end receiver has been realized on 0.13-mum RFCMOS technology. The front-end uses only one fixed frequency PLL and VCO on a superheterodyne architecture to down-convert two RF (radio frequency) signals into two IF (intermediate frequency) signals in the range of 50 MHz to 150 Mhz. L1 and E1 signals are directly converted on one channel with one mixing stage. L2, E6, E5, E5a, E5b signals are down-converted with a double stage (two mixers) conversion. The two IF down-converted channels are filtered and then undersampled by two on chip ADC (analog to digital converter). The satellite channels can be selected and reconfigured only by changing the ADC sampling frequency according to the frequency plan and the off chip RF/IF filters. No PLL and VCO reconfiguration is need. |

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.
