Abstract | This paper presents the design of an ultra wideband (UWB) low noise amplifier (LNA), operated in the range from 3.1 to 10.6 GHz, with noise canceling technology. A two-stage topology is adopted to implement an LNA based on the TSMC 0.18-um process. The first stage is the cascode configuration that is used to exploits negative feedback to enhance the bandwidth. In order to achieve simultaneously output impedance matching, the addition of a common drain is used behind the cascode stage to provide better output matching. And an RLC shunt-shunt feedback is used to attain the broadband gain requirement in the second stage. Noise figure of this LNA with noise canceling is below 3 dB in the range from 3.1 to 10.6 GHz. The simulated results show good performance of $S_{21}$ above 11 dB, and the flat 3-dB bandwidth covering this ultra wideband. The total circuit consumes a very low power of 27 mW. |

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.
