| Abstract | Many military electronic systems experience thermal transient pulses, in the sub-second range, during operation. Transient thermal solutions are being developed to address these transient pulses. In order to determine the performance of these thermal solutions, precise measurement of device junction temperature during the pulse is critical. Researchers have been patterning heaters onto chips using high temperature coefficient of resistance materials, thus allowing the use of the heater as a resistance temperature detector (RTD). For a given RTD material, in order to increase the sensitivity, a high resistance value is required; however, this equates to high voltages needed to get high heat fluxes. This work aims to design a test chip which balances between the instrumentation preferring a large resistance and the desire to maintain reasonable input voltages prompting a low resistance. This work demonstrates a novel multi-functional thermal test chip, which consists of 25 high resistance RTDs connected in parallel. This parallel connection strikes the desired balance by allowing a small overall chip resistance while allowing probing on a much higher resistance single RTD. Furthermore, this design allows optional temperature sensing at multiple locations on the chip’s surface, the possibility to create thermal gradients by controlled powering of individual resistors at different locations on the chip’s surface, and uniform heat flux over the entire chip surface. |

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.
