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 as a base. The text book "Analog Integrated Circuit Design" by David Johns and Ken Martin, John Wiley, 1997, is recommended for further reading. However, we will essentially discuss two research papers, one with lectures 1-7, the other with lectures 8-12. The paper references are given below.
Lecture 01: Introduction, Poles and Zeros, Driving-Point Signal-Flow Graphs
Lecture 02: Gm-C filters from a signal-flow point of view
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
Lecture 07: 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.
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
Lecture 11: Sigma-delta PWM for class-D audio and other Sigma-delta tricks
Lecture 12: 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.

Requirements to qualify for the exam (Testatbedingung)
There will be 12 exercises. You need to hand in solutions of eight of them.
Exam
The oral exam has three phases:
- 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.
- 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.
- 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.
