Abstract | Simultaneous switching noise (SSN) and electromagnetic radiation were intensively examined experimentally by using different test LSIs and packages. Two types of test LSIs have been designed and fabricated in 0.25 um CMOS process. One was with on-chip decoupling capacitance (ODC), and the other was without ODC. Then, two types of packages; quad flat package (QFP) and chip scale package (CSP) were used for housing them. First, SSN and radiated emission for the combination of two types of chips and two types of packages were measured by exciting output circuit and core logic circuit independently. QFP with larger package inductance showed larger power/ground fluctuation than CSP. On the other hand, QFP showed smaller emission properties than CSP. It is because package inductance worked as a filtering component. For both packages, every harmonics was reduced for the core circuit operation due to ODC, while it has been found that only even-order harmonics were dramatically decreased for the output buffer circuit operation |

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.
