Analog Signal Processing and Filtering Autumn 2017 (not final; editing work in progress)

Wiki start address: https://people.ee.ethz.ch/~haschmid/asfwiki/

User Name and Password for downloading documents from this web site are available from the maintainer (see signature below). I will require some sort of proof that you are a student associated with a Swiss unversity, for example a Legi-Nummer.

Lectures

The lectures use handwritten notes and a few research papers as a base.

• Handwritten Notes

• Papers: see Lecture pages.

The text book "Analog Integrated Circuit Design" by Carusone/Johns/Martin can help for further reading. The book is VERY expensive, but on request you can get a "Hörerschein" from me which allows you to buy one for CHF 99.--.

This year's programme

• Lecture 03: Current-Mirror OTA, output with cascodes, OTA with real resistor

• Lecture 04: Inductor simulation, impedance converters, and LC filter simulation, which means replacing L by active circuits

• Lecture 05: Current conveyors, current-feedback opamps and how to build filters with them

• Lecture 06: Specification and quality of signal processing circuits: noise, flicker noise, power, harmonic distortion, PSR, CMR, HD, IMD, SNR, SNDR, SFDR, and figures of Merit

• Joker Lecture: An introduction to doing statistical evaluations in science

• Lecture 08: Switched-capacitor filters, kT/C noise, chopping, and correlated double sampling.

• Lecture 09: Sigma-delta converter fundamentals, loops, stability etc.

• Lecture 10: Higher-order sigma-delta converters

Not in this year's programme

• In-depth discussion of the paper "A Wide Tuning Range Gm-C Continuous-Time Analog Filter" by Tien-Yu Lo et. al., IEEE Trans. CAS-I, vol 54, no 4, pp 713-722, April 2007.

• In-depth discussion of the paper "A CMOS Smart Temperature Sensor ..." by Michiel A. P. Pertijs et. al., J. Solid-State Circuits, vol 40, no 12, pp 2805-2815, December 2005.

Exam

The oral exam has three phases:

1. The student is asked with which topic she or he wants to start, and then gets a simple question to start with. In this phase, the examiner asks questions to test how well the student knows the chosen topic. If this phase is done well, a '4' is guaranteed.
2. In this phase, the examiner lets the student make links from the chosen topic to other topics from the course. If this phase is done well, a '5' is given.
3. In this last phase, the examiner asks questions to which the student cannot have an answer. If the student makes good solution attempts using the material from the course, a '6' is given.

If possible, the examiner announces the phase changes.

A student asked what would constitute a topic, this is the response: The scope of the chosen topic is up to you. Choose it so you can show in sufficient detail your knowledge about it. For example some people chose to talk about sigma-delta converters including noise shaping of different order, which worked out well for them. You could also pick out some detail (e.g. the "gain" in a sigma-delta converter or a particular interesting circuit for the application of Mason's rule) and go more in depth. What you probably shouldn't do is try to argue about why it should be called delta-sigma instead of sigma-delta for ten minutes, and you also shouldn't try to summarize the whole lecture. Brownie points for any topic we don't hear more than once. One approach is to take something that sparked your interest during the lecture and prepare it in detail. If you are interested in what you are talking about, it's likely that we will be, too. Misjudging the scope has not been a problem in the past. Use common sense.
