ASF: Analog Signal Processing and Filtering

Spring semester 2012

Prof. Dr. Hanspeter Schmid

27 hours of lectures and 25 hours of exercises

Goal

This lecture is about analogue integrated filters. The goal of this lecture is to present the theoretical concepts underlying filters and amplifiers in an intuitive manner, such that the students intuitively understand integrated filters. Together with the lecture ''Analog IC Design'' by Prof. Huang, where the sizing and optimisation of transistor circuits is taught, this lecture prepares the students for a prospective job in analogue-IC design

Contents

• Introduction, poles, zeros, driving-point signal-flow graphs
• Gm-C filter theory and implementation
• Amplifiers used for signal processing: OTAs, opamps, current feedback opamps and current conveyors
• Single-amplifier biquadratic filters
• Gyrators and impedance converters
• Switched-capacitor circuits, correlated double sampling, chopping
• Sigma-delta A/D converters: simple converters, higher-order converters, digital filter and system aspects

Prerequisites

• Laplace transform and Z transform
• Basic understanding of signal processing theory
• Basic understanding of transistor operation

Lecture notes, Book

A large part of the lecture is based on the book ''Analog IC Design'' by David Johns und Ken Martin, John Wiley and Sons, New York, 1997. Two weeks before the semester begins, the lecture assistants start selling the book. All other documents will be distributed free of charge.

Credits

The condition for getting credits is the active participation in the lecture in terms of the presentation of a scientific paper.
