| Abstract | An electromagnetic analysis for the practical implementation of on-chip antennas to be used as wireless IC interconnects is presented. The undesired electromagnetic signal coupling between the on-chip antennas and the metal interconnects is characterized under varying geometries and placement of the metal interconnects. The variations in the transmission gain between the antenna pair due to the typical complementary metal oxide semiconductor (CMOS) manufacturing requirements are presented. Using a 3-D finite element method (FEM) based full wave electromagnetic solver, it is shown that the antenna characteristics are significantly impacted by the presence of the essential epitaxial layer and the required minimum metal utilization. It is also shown in a 250nm CMOS technology that there can be a significant electromagnetic signal coupling between the on-chip transmitting antenna and the metal interconnects on a die (-12.09dB for a 1.6mm long, 2μm wide interconnect at a distance of 1μm from the antenna). Design considerations are presented for the metal interconnects in the presence of on-chip antennas in order to minimize the undesired electromagnetic signal coupling. |

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.
