*Dr. Nagendra Krishnapura*

He graduated with a Ph.D. from Columbia University, New York in Oct. 2000. He worked at the Columbia Integrated Systems Laboratory under the guidance of Prof. Yannis Tsividis in the area of nonlinear analog signal processing for low power integrated circuits. He obtained his B. Tech. degree in electronics and communications engineering from the Indian Institute of Technology, Madras, in 1996. Between 2000 and 2005, He worked as a senior design engineer at Celight, Inc. and Multilink(later Vitesse Semiconductor) where he designed integrated circuits for high speed communications. From 2003 to 2005, he was an Adjunct Assistant Professor and taught courses on Analog Circuit Design at Columbia University.

In mock counselling 2013 applicants will basically have to placed approximately facts such as the vigorous and the symbols so that they can get the list of the colleges they are supposing form the earlier year's opening and the closing ranks.

ReplyDeleteVery useful, where can I get the notes/slides?
