Back to the Future: Analog Signal Processing

 

Speaker: Boris Murmann, Stanford University

Time: October 23rd (Thursday) evening 6.30 pm-8.30pm.

Abstract:

In the early days of my engineering career, analog circuit design was viewed as doomed and no longer needed in future systems that will be almost entirely digital and rely on standard analog interfaces that need no further optimization. A we all know, this was wrong. Nonetheless, it is true that in most modern systems, the analog interface often plays only a minor role in the overall signal processing function. This is also evidenced, for example, by our constant craving for “software defined” devices in which all available information is dumped into the digital domain and sorted out using purely digital processing.

In this talk, I will review a number of research ideas in which analog blocks participate more actively in the acquisition, selection and processing of the desired information. We will discuss concepts related to “fooling Nyquist” and extracting desired analog-domain information using low-rate and low-bandwidth observations. In addition, we will investigate the potential for mixed-signal co-processors in machine learning algorithms and other applications that can benefit from approximate computing and analog pre-processing.

 Bio:

Boris Murmann is an Associate Professor of Electrical Engineering at Stanford University. He received the Ph.D. degree in electrical engineering from the University of California at Berkeley in 2003. From 1994 to 1997, he was with Neutron Microelectronics, Germany, where he developed low-power and smart-power ASICs in automotive CMOS technology. Dr. Murmann’s research interests are in the area of mixed-signal integrated circuit design, with special emphasis on data converters and sensor interfaces. In 2008, he was a co-recipient of the Best Student Paper Award at the VLSI Circuits Symposium in 2008 and a recipient of the Best Invited Paper Award at the IEEE Custom Integrated Circuits Conference (CICC). He received the Agilent Early Career Professor Award in 2009 and the Friedrich Wilhelm Bessel Research Award in 2012. He currently serves as an Associate Editor of the IEEE Journal of Solid-State Circuits, the Data Converter Subcommittee Chair of the IEEE International Solid-State Circuits Conference (ISSCC) and as a program committee member of the European Solid-State Circuits Conference (ESSCIRC). He is an elected AdCom member of the IEEE Solid-State Circuits Society.
