| Abstract | Printed circuit boards (PCBs) are one source of radiated EMI with digital components the culprits. To minimize development of common-mode currents within the silicon package of large current consuming circuits, a stable power distribution network (PDN) is required. Any noise (bounce) on either the power or 0 V reference (ground) plane may cause simultaneously switching noise (SSN) or signal integrity (SI) problems, as well as EMI. In addition, if planar bounce exceeds margin levels, components may not function. To ensure a stable PDN is present, decoupling capacitors and buried capacitive structures are mandatory, along with minimizing loop inductance. The uniqueness of this research lies in analyzing planar bounce that may exceed voltage margin levels from reflected EM waves that propagate back to components from the physical edge of the PCB. The edges of a PCB are in reality a high-impedance, non- terminated signal transmission line stub. With each reflection, ringing occurs. The magnitude of this ringing may cause digital components to have SSN and/or EMI problems. Popular board edge termination techniques are invested to determine if a designer should be concerned with reflected wave switching noise on either a power or 0 V reference plane, which cannot be removed by capacitive structures or decoupling. |

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.
