| Abstract | In this paper, a dual-band current-reused low noise amplifier with the band-switching of LC-resonances is designed and measured. Cascading series and parallel LC resonant networks are used to arrive at the matching of reflection coefficient at the input and output terminals. An inter-stage band-switching LC resonant network is used to suppress the signal leakage through the path from the drain of input transistor to the source of cascoded transistor at the frequency bands around 2.3 GHz and 5.2 GHz. This will result in band-switching dual-band transfer characteristics. Simulated S11 and S22 are lower than -10 dB. Simulated maximum gains are 17 and 14.5 dB for the two frequency bands, respectively. The simulated noise figures are less than 3.5dB at the two frequency bands. The power consumption is 8.1 mW. The measured low and high central frequencies are shifted to 2.9GHz and 5.5GHz, respectively. |

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.
