| Abstract | This paper presents the design and simulation of a CMOS ultra-wideband differential low noise amplifier with air-suspended MEMS inductors substituting standard planar spiral inductors. Air-suspended MEMS inductors offer higher quality inductance and higher frequency of operation when compared to monolithic spiral planar inductors. This extends the capabilities of a mixed-signal CMOS process, allowing for a high gain, full spectrum, 3.1-10.6 GHz UWB low noise amplifier. The basic architecture of the LNA designed herein exhibits a differential amplifier core with active input and output impedance matching. Simulations reveal that the LNA maintains a gain of 13.0 dB with a plusmn0.3 dB ripple over the band of 3.1-10.6 GHz. Despite the use of an active input matching stage, the LNA achieved a simulated noise figure ranging from 3.5-4.2 dB over the band of operation. The input and output active matching stages maintain less than -10 dB reflection coefficients with a 50 Omega termination over the desired frequency range of operation |

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.
