He was with Philips Gloeilampen Fabrieken, Eindhoven, The Netherlands, in 1978 where he worked on the design of bipolar differential amplifiers. From 1979 to 1983, he was employed by Hughes Aircraft Company, Newport Beach, California, working in the areas of custom IC design, software compatible gate array design, one- and two-dimensional device modeling, circuit modeling, and double level metal process development. From 1983 to 1991, he was employed at Hughes Aircraft Company, Carlsbad, California, rising to the position of Manager of the Signal Processing Design and Test Department, responsible for the design and test of high performance VLSI/VHSIC CMOS and BIMOS digital and analog IC's, the development of supporting design and test methodologies and CAD tools, functional and parametric test, and the development of high performance and high resolution DSP and oversampled systems.
Dr. Friedman has been with the Department of Electrical and Computer Engineering at the University of Rochester, Rochester, New York, since 1991, where he is a Distinguished Professor and Director of the High Performance VLSI/IC Design and Analysis Laboratory. He previously was the Director of the Center for Electronic Imaging Systems. He is also a Visiting Professor at the Technion - Israel Institute of Technology. He also directs the Technion Advanced Circuits Research Center (ACRC). His current research and teaching interests are in high performance synchronous digital and mixed-signal microelectronic design and analysis with application to high speed portable processors and low power wireless communications.
He has authored twelve book chapters and many papers in the fields of high speed and low power CMOS design techniques, interconnect and substrate noise, pipelining and retiming, three-dimensional integration, and the theory and application of power and synchronous clock distribution networks.
Dr. Friedman has also authored or edited sixteen books, including Clock Distribution Networks in VLSI Circuits and Systems (IEEE Press, 1995), High Performance Clock Distribution Networks (Kluwer Academic Publishers, 1997), Analog Design Issues in Digital VLSI Circuits and Systems (Kluwer Academic Publishers, 1997), Timing Optimization through Clock Skew Scheduling (Kluwer Academic Publishers, 2000 and 2009), On-Chip Inductance in High Speed Integrated Circuits (Kluwer Academic Publishers, 2001), Power Distribution Networks in High Speed Integrated Circuits (Kluwer Academic Publishers, 2004), Multi-Voltage CMOS Circuit Design (John Wiley & Sons Press, 2006), Power Distribution Networks with On-Chip Decoupling Capacitors (Springer Verlag, 2008 and 2011), Three-Dimensional Integrated Circuit Design (Morgan Kaufmann, 2009), and High Performance Integrated Circuit Design (McGraw-Hill Publishers, 2012).
