| Abstract | This paper presents the design of a CMOS low noise amplifier (LNA) suited for UMTS wireless standard. This standard of third wireless generation aims to focus on the already existing process in order to develop and improve actual service systems capacitance, like cordless and satellite systems. This objective can be obtained by improving system gain, increasing transmission data rate, etc. The designed amplifier uses differential structure, to ensure linearity and low noise figure. The noise model in this circuit is well mastered, however non linearity phenomenon is still very hard to encounter. For this reason, heuristics methods couldn't be applied to make transistors and passive element's sizing. In order to obtain a trade between linearity and noise figure, we propose here to use an optimization method based on experience plans. We designed an LNA with AMS 0.35/spl mu/m CMOS process. It provides a 19 dB gain at 2.14 GHz timing frequency and 2.4 dB noise figure (NF). The power consumption is 90 mW at 2.5 V power supply voltage. Simulation results are compared with the theoretical prediction and have shown the efficiency of our design methodology. |

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.
