Analog Signal Processing and Filtering

Fall Semester 2024

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

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.
