| Abstract | Base current reversal phenomenon is newly observed in a CMOS compatible high gain n-p-n gated lateral bipolar transistor. We attribute this phenomenon to avalanche generation as verified experimentally and by two-dimensional device simulation. Detailed investigation reveals that: (i) the multiplication ratio increases exponentially with the collector voltage or equivalently the peak field at the surface collector corner; and (ii) the multiplication ratio is independent of not only the low level base-emitter forward biases applied but also the base width of the transistors fabricated by the same process. Design guideline for suppression of the base current reversal has been established such as to fully realize the potential of the gated lateral bipolar transistors, i.e., a very high current gain of 11,600 can be maintained as long as the power supply voltage is less than the critical value of 1.78 V. On the other hand, new application directly employing this phenomenon has been suggested. Comparisons between the base current reversal phenomenon in the gated lateral bipolar transistor and that in the vertical bipolar transistor have also been performed and significant differences between the two have been drawn and have been adequately explained.< |

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.
