Low-Power VLSI Circuits and Systems

Ajit Pal is currently a Professor in the Department of Computer Science and Engineering at Indian Institute of Technology Kharagpur (IITKGP). He received his M.Tech. and Ph.D. degrees for the Institute of Radio Physics and Electronics from Calcutta University in 1971 and 1976, respectively. Before joining IITKGP in the year 1982, he served at Indian Statistical Institute (ISI), Calcutta; Indian Telephone Industries (ITI), Naini and Defense Electronics Research Laboratory (DLRL), Hyderabad in various capacities. He was designated professor in 1988 and served as Head of Computer Center from 1993 to 1995 and Head of the Computer Science and Engineering Department from 1995 to 1998. His research interests include embedded systems, low-power VLSI circuits, sensor networks and optical communication. He has served as the principal investigator of several sponsored research projects including ‘Low Power circuits’ sponsored by Intel, USA and ‘formal methods for power intent verification’, sponsored by Synopsis (India) Pvt. Ltd. He has over 150 publications in reputed journals and conference proceedings and three books entitled Microprocessors: Principles and Applications, Microcontrollers: Principles and Applications and Data Communication and Computer Networks. He is a Fellow of IETE, India and Senior Member of IEEE, USA.
