| Abstract | The benefit of an on-chip antenna is the possibility for smaller size and fewer external components. If an on-chip antenna is combined with power scavenging circuits to eliminate the external battery, it is possible to achieve true fully integrated transceivers. However, there are many challenges to overcome and compromises to be made. The use of an on-chip antenna will typically result in lower communication range, and the impedance of such antenna may not be as convenient for interfacing. Similarly, the choice of operating frequency involves a tradeoff between antenna efficiency and power consumption in the active circuitry. In order to operate with minimum power to allow for the possibility of using scavenged power, it is possible for circuitry to be shut down when it is inactive; however, this requires more careful consideration of synchronization circuits. These are some of the issues that will be discussed in the context of several examples including an RF transceiver designed for 5.2 GHz operation and intended for short range communication with biomedical sensors. |

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.
