| Abstract | This paper presents a 5.8 GHz low voltage down-conversion mixer design integrated in a TSMC 0.18 /spl mu/m CMOS process. The proposed method features that an RF input stage converts the RF input voltage to current, which is coupled to the core of Gilbert Cell using current mirror. This implementation eliminates the current source transistor at bottom and furthermore reduces the supply voltage. Common-mode feedback is used for the active load of the mixer. The LO frequency is at 5.6 GHz. The designed mixer requires only a 1.5 V supply voltage and consumes 11.78 mW DC power. At 5.8 GHz, this mixer has single-sideband noise figure (SSB NF) of 13.6 dB, with input return loss of -18 dB, with output return loss of -26.4 dB, Third-order Input Intercept Point (IIP3) of -10.66 dBm, and conversion gain of 10.4 dB. |

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.
