| Abstract | In this work it is presented a design tool to estimate the figures of merit of a radiofrequency power amplifier (RFPA) based on the envelope amplifier (EA) design for an EER (Envelope Elimination and Restoration) application. Using as the input data the transfer function of a buck derived converter for an envelope amplifier application, the main figures of merit of the complete amplifier can be obtained. The input data can be defined either analytically, by measurements or by simulation. Different control strategies have been analyzed and compared at the simulation level. Additionally, the non-linearities of the envelope amplifier can be analyzed and quantified. The proposed design tool has been validated experimentally for an OFDM, QAM-based modulations and for a two tone test signal. |

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.
