| Abstract | Modeling of the coupling between transmission lines in the practical sense has been an elusive quarry. Since the favorite tool of signal integrity designers is SPICE, the ultimate goal should be translation of the mathematics of coupled mode analysis into a simple SPICE formulation. This investigation presents a method to simulate the parasitic coupling between transmission lines in structures where complete isolation is impractical. The conventional mathematical analysis of such coupling does not suggest a simple SPICE solution, so a farther analysis of cause-effect and elimination of unimportant terms resulted in a set of models which uses the transmission line capacitance matrix to create a direct input of parameters to a SPICE subcircuit. This SPICE subcircuit is utilized as an attachment to a previously designed lossy transmission line circuit. The resultant circuit models cross coupling originating from any number of culprits affecting one victim. The circuit requires one victim line and one culprit line, where the assumption is made that all culprit lines carry the same signal. The technique is applicable to single ended and differential pair transmission lines. An HSPICE subcircuit was included to illustrate the ultimate form of the model. |

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.
