Biography

Anil Kumar Kumaran is a Ph.D. candidate in the ELCA research group at the Delft University of Technology since October 2020. He received his B.Tech. degree in Electronics and Communication Engineering from the Amrita Viswa Vidhyapeetham, Coimbatore, India, in May 2015 and the M.Sc. degree in Microelectronics from the Delft University of Technology, Delft, the Netherlands in August 2020. Before joining his Masters, he worked as an Onsite Validation Engineer in Texas Instruments India. His research activity primarily focuses on designing linear and efficient mm-wave transmitters for 5G cellular applications.
