Abstract | A 5.8GHz low voltage, high linear and isolation transformer based mixer using 0.18mum CMOS process for WLAN receiver was investigated. The proposed fully integrated transformer featured that biasing, coupling, and filtering functions in an RF input stage commutated the input RF voltage to current, which was coupled to local oscillator (LO) switching pairs. This implementation excluded the current source transistor at bottom and furthermore reduced the supply voltage. The designed mixer required only a 0.8V supply voltage and consumed less than 10mW DC power. A high third-order intercept point of +3dBm and an input second-order intercept point of +19dBm had been achieved. The excellent LO/RF and RF/IF isolations were achieved up to 54dB and 74dB, 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.
