| Abstract | On-chip, high-frequency clock sources are essential for the future development of superconductor digital circuits and systems. We have developed clock sources for rapid single flux quantum (RSFQ) digital circuits using high-quality long Josephson junction (LJJ) resonant oscillators that offer extremely low jitter. To meet the requirement for time-interleaved clock signals of complementary phase, two-phase 30 and 50 GHz clock sources using LJJ's have been developed with both linear and annular geometry. Unperturbed by reflections from boundaries and collisions among the fluxons (flux quanta), the annular LJJ oscillator has demonstrated superior stability and higher quality factor (>10/sup 6/) than the linear LJJ oscillator. The LJJ oscillator with linear geometry is easier to interface with RSFQ circuitry since it has well-defined boundaries at either end, facilitating a two-phase clock source. On the other hand, multiple clock phases may be derived from an annular LJJ oscillator by connecting interface circuitry at various points around the circular junction, if the interface circuitry does not interfere with the fluxon(s) in the annular junction. Experimental results for two-phase RSFQ clock sources based on linear and annular LJJ oscillators are presented. |

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.
