520.490: Analog and Digital VLSI Systems and Architecture


Fall Semester 2003


Silicon models of information and signal processing functions, implemented in analog and digital CMOS integrated circuits.  Structured design, scalability, parallelism, low-power consumption, and robustness to process variations.  Topics include digital-to-analog and analog-to-digital data conversion, delta-sigma modulation, vector quantization, continuous-time and switched-capacitor analog filters, and adaptive neural computation.

An advanced design project is part of the course.  Students (in groups of two or three) design a complete VLSI system-on-a-chip using the Cadence CAD tools, including layout and verification.  Chips will be fabricated through MOSIS and laboratory facilities will be available for testing after the course.  Students choose projects according to their ideas and field of interest. Example projects done by students in the past include D/A data converters, delta-sigma modulators, delta modulators, focal-plane active imagers, and cochlear filterbanks.

Prerequisite: 520.216 and 520.345, or equivalent.

Grading: 50% homework and midterm; 50% design project.

Classes: ThF, 1-2:30pm, Barton 114.
