Tutorial T2


T2: Operational Amplifiers: Theory, Design and Applications

Presented by: Edgar Sanchez-Sinencio, Jaime Ramirez-Angulo, and Igor M. Filanovsky


Abstract. OpAmp is the main analog building block for both the systems based on discrete elements and systems on silicon. The parameters of OpAmp often define and limit the overall system performance. CMOS technology provides an opportunity to use more complex structural solutions and circuit techniques to improve OpAmp accuracy, power/speed ratio, to add new functional advantages, like low voltage supply operation capability or rail to rail input without the switching point, everything for negligible additional component cost. The circuit techniques that will be demonstrated during this course were proven in design of leading industrial OpAmps.


Edgar Sánchez-Sinencio is currently the TI J. Kilby Chair Professor and Director of the Analog and Mixed-Signal Center at Texas A&M University.   He is the former Editor-in-Chief of IEEE Transactions on Circuits and Systems II.  In November 1995 he was awarded a Honoris Causa Doctorate by the National Institute for Astrophysics, Optics and Electronics, Mexico.  He is co-recipient of the 1995 Guillemin-Cauer for his work on cellular networks.  He was also the co-recipient of the 1997 Darlington Award for his work on high-frequency filters. He received the Circuits-and-Systems-Society Golden Jubilee Medal in 1999. He recently received the IEEE Circuits-and-Systems-Society 2008 Technical Achievement Award. His present interests are in the area of power management, RF-communication circuits and analog and medical electronics circuit design.

Jaime Ramírez-Angulo is Klipsch Distinguished Professor, IEEE Fellow, and Director of the Mixed-Signal VLSI lab at the  Klipsch School of Electrical and Computer Engineering, New Mexico State University   in Las Cruces, New Mexico, USA. His research is related to various aspects of design and test of analog and mixed-signal Very Large Scale Integrated Circuits. He has made numerous contributions to this field which has been reported in over four hundred twenty publications.

Igor M. Filanovsky is currently a Professor Emeritus in the Department of Electrical and computer Engineering at the University of Alberta, Edmonton, Canada. He contributed to four books, Sensor Technology and Devices, L. Ristic, Ed.,1994, Analog VLSI: Signal and Information Processing, M. Ismail and T. Fiez, Eds., 1994), The Circuits and Filters Handbook, W.-K. Chen, Ed., 2009, The Electronics Handbook, J. Whitaker, Ed., 1996, a co-authored  Operational Amplifier Speed and Accuracy Improvement, Kluwer, 2004. He was also a contributor to The Encyclopedia of Electrical and Electronic Engineering, J. Webster, Ed., 1999) and Comprehensive Dictionary of Electrical Engineering, P. A. Laplante, Ed., 1999). Dr. I.M. Filanovsky is the author or co-author of about 250 publications on circuit theory (theory of approximation, theory and technical applications of oscillations, strongly nonlinear oscillations) and applied microelectronics (analog electronic circuits, oscillators and multivibrators, signal-conditioning circuits for sensors). He has 4 patents on electronic circuits.
