Analog Signal Processing and Filtering

Fall Semester 2023

Prof. Hanspeter Schmid

27 hours of lectures and 25 hours of exercises

Location:           CHN E42
Lectures:           Wednesdays, 08:15 - 10:00
Exercises:         Wednesdays, 10:15 - 12:00
Assistants:        Hampus Malmberg

Goal

This course is about analog integrated filters. The goal of this course 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 course ''Analog IC Design'' by Prof. Huang, where the sizing and optimisation of transistor circuits is taught, this course prepares the students for a prospective job in analog-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 script will be made available at the beginning of the course.

Note that a large part of the course is based on the book ''Analog IC Design'' by David Johns und Ken Martin, John Wiley and Sons, New York, 1997. Two copies of the book are available for borrowing at the assistance.

Special Remarks
