Digitally Enhanced Analog Systems

Monday, May 9, 2011

Dr. Fernando A. Mujica

Abstract

Traditional integrated circuit system design methodologies impose boundaries between digital and analog that often result in system inefficiencies in power, performance and/or cost.  The problem can be partially mitigated by the co-specification of the digital and analog partitioning.  However, significant additional gains can be obtained by using signal processing within the inner workings of analog systems.  In this talk, after introducing the rationale behind this type of digitally enhanced analog systems, we will describe some of the applications that we have applied this design methodology to: data converters, digital RF, high-speed serial communications, loudspeaker compensation and adaptive antenna tuning.  We conclude the talk with a list of applications that we believe can also benefit from this design methodology.
