HURWITZ Memorial Lecture: Optimal Design of Analog CMOS Circuits via Geometric Programming

(joint work with Mar Hershenson and Tom Lee) As more ICs incorporate some analog functionality, the demand for analog CMOS design is greatly increasing. Not only will the number of new designs increase, but so will the number of designs that must be ported every 12 months or so to the newest process technology. This increase in demand comes during a great shortage of experienced analog designers. Predictions abound that analog design will become a critical bottleneck for next-generation system-on-a-chip (SoC) designs. In this talk we describe a new general method for optimized design of analog CMOS circuit blocks. We first cast the circuit design problem as a very special type of mathematical optimization problem, called a geometric program, which we then solve using recently developed interior-point methods. The result is a method that can very efficiently determine globally optimal circuit designs, given from specifications (such as on power, area, open-loop gain, bandwidth, etc.). The method can be used for extremely rapid design, performance and trade-off analysis, and porting of analog circuit cells to new technologies. After giving some general background, we describe the underlying optimization method, and explain how the method applies to the design of a common op-amp.

Biographical Sketch:
Stephen P. Boyd received the AB degree in Mathematics from Harvard University in 1980, and the PhD in EECS from the University of California, Berkeley, in 1985. In 1985 he joined the Electrical Engineering Department at Stanford University, where he is now Professor and Director of the Information Systems Laboratory. He has held visiting Professor positions at Katholieke University (Leuven), McGill University (Montreal), Ecole Polytechnique Federale (Lausanne), Qinghua University (Beijing), Universite Paul Sabatier (Toulouse), and Royal Institute of Technology (Stockholm). In 1999, during a leave from Stanford, he co-founded Barcelona Design, and still serves as its Chief Scientist and a Director. He was a member of the Board of Governors, IEEE Control Systems Society, from 1989 through 1992, is a Fellow of the IEEE, and has been a Distinguished Lecturer of the Control Systems Society since 1993. Awards and honors for his research in control systems engineering and optimization include the AACC Donald P. Eckman Award, an ONR Young Investigator Award, a Presidential Young Investigator Award, and an IBM faculty development award. He has given many plenary lectures in both optimization and control. He has received several awards for teaching and lecturing, including the 1994 Perrin award for outstanding undergraduate teaching in Stanford's School of Engineering, and the 1991 ASSU Graduate Teaching Award. He is the author of two books: Linear Controller Design: Limits of Performance} (with Craig Barratt, 1991) and Linear Matrix Inequalities in System and Control Theory, (with L. El Ghaoui, E. Feron, and V. Balakrishnan, 1994). He is currently working (with Lieven Vandenberghe) on a book on convex optimization with engineering applications. His interests include computer-aided control system design, and convex programming applications in control, signal processing, and circuit design.
