| Abstract | A novel 0.13 mum CMOS low-voltage high-linearity mixer for direct-conversion UWB receiver is presented. The topology of the wideband mixer employing a shunt resistor in input-matching network is analyzed in details. A CMOS inverter with current-reuse technology is used in the transconductance stage. The transconductance stage and the switching stage are ac-coupled with capacitors. LC resonators were adapted in design to replace commonly used current sources. The methods of improvement on linearity, gain and noise are analyzed. The ICs were fabricated with SMIC 0.13 mum RFCMOS technology. The measured IIP3 of 10.2 dBm, with a power gain of -4.2 dB, and SSB noise figure of 12 dB were obtained. A low dissipating power of 5.1 mW at 1 V supply voltage was also achieved. |

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.
