| Abstract | A direct conversion CMOS RF front-end for IEEE 802.11a wireless LAN is presented. The RF front-end is fully integrated, including LNA, SDC, and direct-conversion I/Q mixers using 0.18/spl mu/m CMOS technology. The RF front-end provides dual gain mode, 25dB or 15dB, to alleviate the linearity requirements of the following stages. It also presents low noise figure and high linearity in the frequency band of interest. The noise figure, IIP3, and IIP2 are 4.9dB, -14dBm, 34.6dBm for high gain mode, and 10.8dB, -3.2dBm, 45.4dBm for low gain mode, respectively. The power consumption of the RF front-end is considerably reduced by using zero-IF architectures and only 22.8mW from a 1.8V supply voltage. The corner frequency of the flicker noise is only 60KHz. The bondpad and package parasitics are also taken into account for the design and simulation. |

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.
