Abstract | As clock speeds increase into the GHz regime and rise times decrease into the picosecond regime, the interaction between capacitors and the power/ground planes of the package, interposer, or board on which they are mounted becomes vitally important to the performance of a power delivery system. To include the interaction, this paper provides an integrated model for a discrete capacitor mounted on pads over vias connected to power/ground planes with degassing holes. The mutual inductance between capacitor pads, vias, and power/ground planes are completely modeled. Our modeling results show that the mutual inductance drastically changes the total loop inductance as compared to the self inductance of the capacitor. In some cases, it even reduces the total effective loop inductance. To validate the integrated modeling method, a test package is built. A measurement technique is introduced to evaluate the total loop inductance of the test package with various capacitors. The predicted results matched very well with measured data which give a high confidence on this predicting model and demonstrate the importance of modeling the interaction between capacitors, vias, and planes. |

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.
