| Abstract | In this paper, inductive feedback approach is applied for bandwidth extension of Common Source Transimpedance Amplifier. The effect of parasitic capacitances of the MOS transistor is reduced using this approach. The process of zero-pole cancellation for extending the bandwidth of the amplifier is explained. Moreover, a wideband three stage transimpedance amplifier based on common source amplifier is introduced. To demonstrate the feasibility of the technique, the transimpedance amplifiers are simulated in a well-known CMOS technology (i.e. 90nm STMicroelectronics). The single stage amplifier achieves 3-dB bandwidths of 32.1GHz, in the presence of a 50fF photodiode capacitances and 5fF loading capacitance while only dissipating 2.03mW. The three stage amplifier achieves bandwidths of 42.8GHz in the presence of 50fF photodiode capacitance and 5fF loading capacitance. The power consumption for the 3-stage transimpedance amplifier is 6.1mW. For all the structures noise performance is competitive in comparison with other works. Eye diagram evaluation for each topology shows the capability of the technique to pass high data rate effectively without inter symbol interference. |

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.
