Abstract | This work presents the analysis and design of a novel transformer-based power combining network for an efficient outphasing power amplifier (PA). The proposed power combining network was implemented on PCB together with two 65nm CMOS class-E PA's. Measurements show a peak output power of more than 30dBm over a 29% bandwidth around 700MHz. The peak output power at 700MHz equals 33.9dBm. The 10dB back-off efficiency is larger than 27.3% over the same 29% bandwidth. The 6dB back-off efficiency is larger than 46.4% over this bandwidth. The drain efficiency at 650MHz is larger than 50% over a 10dB power back-off range, which is, to our best knowledge, the highest back-off efficiency reported in a CMOS outphasing PA to date. |

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.
