VLSI Devices : Modeling and Simulation by Prof. S.K. Lahiri sir

Samir K. Lahiri obtained M.Tech. and Ph.D. in Radio Physics and Electronics from the University of Calcutta in the years 1966 and 1971 respectively. He joined the faculty of Indian Institute of Technology Kharagpur in the  Department of Electronics & Electrical Communication Engineering in November 1971. Since then he served I.I.T. Kharagpur in various capacities: He became Professor in 1985, Co-ordinator – Microelectronics Centre in 1989, Dean – Sponsored Research and Industrial Consultancy (1997 – 2000), Chairman – Advanced Technology Centre in 1998, and the Deputy Director of the Institute during 2002 – 2005.. He took active role in the development and expansion of teaching and research programmes in microelectronics/VLSI, semiconductor devices, microelectromechanical sensors (MEMS), integrated optics and surface-acoustic-wave (SAW) devices. He has led research groups in challenging R & D activities in the above areas, sponsored by various agencies, which resulted in development of silicon linear bipolar ASICs, ECL gate chips, MEMS such as silicon micromachined thermal detectors, accelerometers, quartz micromachined gyro-chips and DETF accelerometer chips, integrated-optic waveguides and components, special SAW filters, etc. He also played the key role in setting up the Advanced VLSI Design Laboratory, Space Technology Cell and MEMS Design Laboratory in IIT Kharagpur. He has supervised 12 Ph. D. theses and authored about 150 research papers. He was the Secretary, Vice-President and President of IEEE Kharagpur Section in the early 1990s. He serves in various National Level Committees on Smart Materials & Structures, Nanotechnology and VLSI Design and is in the Research Council of CSIO Chandigarh and in various national level committees of ISRO, DRDO, CSIR, NPSM, DSIR, DIT/MCIT and other organisations. He is a Fellow of Indian National
Academy of Engineering.
