Abstract | A low-voltage, low-power ultra-wideband (UWB) low-noise amplifier (LNA) for IEEE 802.15.3a is presented. A simplified Chebyshev filter is used to achieve the input broadband matching. This input network has lower complexity and good reflected coefficient from 3.1GHz to 10.6GHz. An output-matching buffer is designed specially to match for maintaining high gain at upper frequency. Therefore, it can both achieve flat gain over the whole bandwidth and generate more output current. The LNA is simulated based on TSMC 0.18/spl mu/m mixed signal/RF process. With only 1V bias voltage, the LNA can achieve power flat gain of 10dB with input matching of -9.76dB; the minimum noise figure 3.7dB; and input third-order-intercept point (IIP3) of -1dB. The power dissipation is only 7.2mW. |

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.
