| Abstract | Modern VLSI technology is mainly driven by digital circuits because digital circuits has many advantages over analog circuits. By using very small and simple circuits atomic digital functions can be realized. All digital phase locked loops (ADPLL) plays an important role in applications such as Bluetooth, GSM and Wi-Fi. A Time to digital converter (TDC) is the critical part in the ADPLL. The concept of TDC is to sample the outputs of all delay elements at the same time. To know the performance of TDC we are analyzing various TDC architectures using buffers and inverters. Flash type TDC have less resolution which uses single delay line. Whereas Vernier delay line TDC uses two delay lines which resolves finely. Replica delay line TDC reduces mismatches among the delay cells. The Vernier ring TDC places the Vernier delay cells in a ring format and reuses them for the measurement of the input time interval. This TDC architecture will give high resolution than conventional TDC models. The power consumed by various TDC architectures are analyzed. Analysis are done by using Xilinx and cadence virtuoso gpdk 180nm technology. |

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.
