| Abstract | This work presents the design and the manufacturing of an ultra wide band power amplifier specially designed to deliver maximum available power to a miniaturized antenna developed for biomedical applications. The chip is designed using a low cost 0.25μm 95GHz $f_{max}$ SiGe-HBT-BiCMOS process technology. The amplifier operates from 1.5GHz up to 10GHz that gives the advantage of having high resolution radar system. The amplifier has a low output impedance to match the antenna's impedance. The measurements of the chip are performed in 50Ω system to extract the scattering parameters and simulate it with the antenna. The estimated gain is 11dB with input reflection coefficient less -10dB and serves as a matching network between the 50Ω input and the low impedance antenna. The maximum estimated output power of the amplifier is 5.5dBm at frequency 8GHz with power added efficiency of 3%. The chip consumes a low power of 96mW and has an area of $0.84mm^{2}.$ |

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.
