Abstract | A 5.8-GHz two-stage high-linearity low-voltage CMOS low-nose amplifier (LNA) has been developed in a 0.35-/spl mu/m pure digital CMOS technology without any additional mask or post-processing steps. A two-stage architecture is used to simultaneously optimize the gain and noise performance. Based on the modified CMOS model valid for RF range, the LNA with fully on-chip input, output and inter-stage matching was designed to verify the two-stage LNA architecture. This LNA chip achieves measured results of 3.2-dB NF, +6.7-dBm IIP3 and -3.7-dBm output P/sub 1dB/ at 5.8 GHz. A figure-of-merit for linearity (output IP3/P/sub DC/) of 1.2 is achieved, which is believed to be among the best reported for a CMOS low-noise amplifier operating at 5-6 GHz ISM band. The effective circuit area is only 0.63 /spl times/ 0.46 mm/sup 2/. |

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.
