| Abstract | The spatial resolution of microwave and mmWave imaging systems can be improved by an increase of their operating frequencies into the submillimeter-wave range (300GHz to 3THz). Electronic terahertz sources and receivers are presently dominated by III/V semiconductor and waveguide packaging technologies. Multipliers and mixers capable of an output power of 1.4mW at 875GHz [1], as well as a conversion loss of 9.25dB at 850GHz [2], have been demonstrated in remote sensing and radio astronomy applications. However, short-range active terahertz imaging systems exhibit less stringent link-budgets, thus opening up new opportunities for highly integrated low-cost silicon TX and RX front-ends. Previous circuit design examples include a 410GHz CMOS VCO in a 45nm technology capable of an output power of −47dBm [3], as well as a 650GHz subharmonic receiver with a 44dB noise figure [4]. In this paper, recent advances in SiGe HBT device technology [5] are used to demonstrate a 820GHz TX/RX chipset for active terahertz imaging applications. |

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.
