| Abstract | Circuit modeling of high-frequency devices described by tabulated multi-port parameters has generated immense interest during the recent years. In most cases, simple equivalent circuit models (S-ECM) are available to the designers, which correlate well with the measured parameters at certain frequencies, however, deviate at others. Traditional efforts to improve equivalent circuit models are device-specific, laborious and ad-hoc in nature. This paper presents an efficient and automated algorithm to identify appropriate elements for adding to the S-ECM at arbitrary locations so as to correct for frequency-dependent errors. These elements are given as rational functions which can be synthesized into frequency-independent elements. In addition, these functions are found without performing expensive nonlinear optimization. The new method enables the designers to retain their existing physical models while providing a means to capture high-frequency effects accurately |

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.
