| Abstract | The paper reviews the state-of-the-art in IC temperature sensors. It starts by revisiting the semiconductor theory of thermodiodes and thermotransistors, continues with the introduction of IC temperature sensors, the concepts of VPTAT - voltage proportional to absolute temperature and IPTAT (current proportional to absolute temperature) and discusses the possibility of use of parasitic bipolar transistors as temperature sensors in pure CMOS technology. The next section demonstrates the very high operating temperature of a dasiaspecialpsila thermodiode, well beyond the typical IC silicon junction temperature. This is achieved with a diode embedded in an SOI CMOS micro-hotplate. A discussion on the temperature limits of integrated temperature sensors is also given. The final section outlines the prospects of IC temperature sensors. |

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.
