| Abstract | The ever-growing demand to high-speed transmission of data has forced the designers to make faster and much more reliable circuits and systems for users. Among many of methodologies for data formats to be transmitted, the binary data is of great interest. There are various pulse code modulations (PCM) for transmission of binary data among which, non return to zero (NRZ) and return to zero (RZ) are well-known. RZ is more reliable and easier to use in comparison with NRZ but it is slower. Since there is no zero between any two bits in NRZ, its bit rate is two times more than that of RZ in the same conditions. But this reality makes the designers to consider an edge detector for NRZ data. This paper introduces a novel edge detector designed for 2.5 Gb/s clock recovery circuit. This baud rate represents the free-running frequency of phase locked loop (PLL). The advantage of this edge detector is its flexibility to encounter with frequency changes. Moreover, it doesn't dissipate constant power meaning that its dissipated power is proportional to the frequency of the received data. Therefore the jitter and extra power dissipation produced by conventional edge detectors are removed. Finally, the simulation of this edge detector for a 0.18 mum technology and its comparative results are given. |

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.
