| Abstract | A fully differential analog multiplier for wideband operations is presented. The circuit consists of a p-MOSFET common-gate differential pair input stage for wideband impedance matching, a p-MOSFET Gilbert quad as a multiplier stage, and active loads. The circuit has been designed and fabricated in 90-nm CMOS. The test-chip area is 560 × 700 μm2. The overall power consumption is 3.7 mW from a 1.2-V power supply. In the case of input monocycle pulses with duration time of 700 ps, the measurements show an input-output energy ratio equal to 2, a conversion gain of 12.7 dB at intermediate frequencies in the range of 0.001-10 MHz for input tones in the range of 2-4 GHz, a noise figure of 14.4 dB (minimum) and compression points of -3.5 and -2 dBm for the two inputs. The performance of the proposed multiplier favorably compares with the state of the art. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
