| Abstract | In this paper the new type of UWB LNA is presented. The amplifier has a novel feedback topology and load circuit that allows the designer to obtain high voltage gain and matching in the wide frequency range from 3.1 GHz to 10.6 GHz without cascading, current reuse technique and without an additional matching circuit. The key point of the amplifier is the source degeneration with resistive shunt series feedback and the load circuit based on combined parallel-series resonance circuit. The voltage gain of the amplifier is 11 dB, the matching is better than −10 dB, the noise figure lies between 3.2 and 4 dB in the whole frequency range. The value of CP1dB is −15 dB at the frequency near the amplitude response maximum 7.6 GHz. The amplifier consumes the power of 11.5 mW from the voltage supply 1.8 V. These characteristics are obtained by simulation of the amplifier using Virtuoso custom design platform, Cadence Design Systems, using 0.18 um CMOS parameters. |

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.
