| Abstract | The design and measurement of two optical receivers with integrated photodiode in 130 nm CMOS is presented. The low bandwidth, which is typical for photodiodes in CMOS technologies, is circumvented by a differential photodiode topology on the one hand and by including an optimized equalizer in the receiver chain on the other hand. The low responsivity of a CMOS photodiode is compensated by a very low-noise design for the differential TIA. The disadvantage of such a low-noise design is its high power consumption. Therefore, a design strategy is presented where part of the circuit is biased in weak inversion. Doing so, the power consumption is decreased from 138 mW for the standard design to only 74.16 mW. Both designs are measured optically with 850 nm modulated light and are able to operate at 4.5 Gbit/s with a BER lower than 10-12. The sensitivities for this BER and speed are - 3.8 dBm and -3.4 dBm respectively. The receivers even work up to 5 Gbit/s for BER values around 10-9. |

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.
