Dr. Kalyan Bhattacharyya
Dr. Kalyan Bhattacharyya currently serves as Associate Professor at the department of Electronics and Communication Engineering, Amrita School of Engineering, Coimbatore. He joined Amrita University in 2015. He obtained MASc by research from McMaster University, Hamilton, Ontario, Canada in 2004 and PhD from Indian Institute of Technology (IIT) Bombay in 2015, both degrees in Electrical Engineering (RF Microelectronics and VLSI Design Branch).
He has worked 8 years with Multinational Industries like joint venture of Philips Telecommunication Industries (6.5 years) and as a Govt. Scientist for around 3 years at Institute for Plasma Research, India. He has done 8 years of Teaching Assistantship during his Masters in Canada and during his PhD at IIT Bombay. He has also worked in IIT Bombay for 1 year, six months as a Research Engineer and six months as a Research Associate (Post-Doctoral). His areas of interest include CMOS RF VLSI Design, Receiver and Transmitter Design for 60 GHz 5G Mobile Communication and 77 GHz Automotive Radar applications, Monolithic Microwave Integrated Circuits, and Nano-scale MOSFET/SoIMOSFET/GaN-HEMT Device Physics and Transmitter design.
Dr. Kalyan's current research project is design, simulation, fabrication (through UMC foundry Brussels) and testing of Low Noise Amplifiers for UWB bands and QVCO in 180nm CMOS for which he has received SEED funding. He has designed and fabricated Microelectronic chips (ICs) through TSMC foundry Taiwan since 2002 and UMC foundry Brussels since 2009 onwards and Characterization in Canada/IITB/IISc/V-NIT. He has published several papers in IEEE including IEEE Transaction on VLSI Systems and IEEE International Conference on VLSI Design. He has presented research papers at the conferences in the USA, Canada, and India. He has four Indian Patents granted on Distributed Oscillator, Tunable Distributed Voltage Controlled Oscillator and Second and Third Harmonic Frequency Distributed Oscillators, all for generating Microwave signals in CMOS technology. He has served as a reviewer for the journal of IEEE Transaction on VLSI Systems and worked with the organizers of IEEE International Conference on VLSI Design. He has given several invited talks and tutorials on CMOS RF/Analog Microelectronic Chip (IC) Design. He has received full Graduate Scholarship for his studies in Canada and complete funding of PhD from “TaTa Consultancy Services VLSI Design” project at IIT Bombay. He is a member of IEEE.
