| Abstract | In this paper, we simulated and analyzed about through-via's signal integrity, (SI)/power integrity, and (PI)/electromagnetic interference (EMI) that goes through the power/ground plane which was caused by the high dielectric material that supports the embedded high value capacitors. In order to evaluate through-via's effectiveness, the simulation condition was operated on the LTCC module for mixed signal system. For the circumstance SI, delay time of signal line and signal quality significantly decrease because of higher parasitic capacitance between through-via's and anti-pads. However, in a situation where the dielectric material is chosen, the EMI's characteristic power/ground plan with embedded high dielectric material shows a better characteristic than when the low dielectric material was chosen. As a result, if the high dielectric material is applied on LTCC module, the mixed module packaging that is made with the digital IC and RF component will be realized as the optimistic design. The simulation structure takes the LTCC process designer guidebook as a basic structure and uses the HFSS/designer tool. When the dielectric constant uses 7.8 and 500, the through-via's that pass through the LTCC module are delay time of 41.4 psec and 56, respectively. When the dielectric constant of 500 is compared with 7.8, the power/ground plane impedance shows a trait lower than several GHz range and effectiveness in the rejection of the resonance mode. When uses the dielectric constant is 500, the EMI level is 7.8 and it is prove that the EMI level improves at maximum 20 dB V/m. |

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.
