Laboratory Design of Integrated Analog and Mixed-Signal Circuits

Module Number: EI78080

Duration: one semester

Occurence: summer semester

Language: German/English

Amount of work

Contact hours: 60

Self-study hours: 90

Total: 150

Description of Achievement and Assessment Methods

The grade of the module is determined by two components:
1. presentation about the designed system (about 15 min) (2/3)
2. evaluation of the simulation results and the generated data sheet (1/3)

Prerequisites (recommended)

Analog and Mixed-Signal Electronics  

Intended Learning Outcomes

After successfully completing the course, the students are able to analyze existing mixed-signal and CMOS circuits regarding their functionality, mark different circuit parts regarding their functionality and classify present state-of-the-art circuit concepts. Furthermore, they are able to verify circuit concepts regarding their advantages and disadvantages for different application. Ultimately they single-handed develop a mixed-signal system according to given specifications and can explain and evaluate the chosen design concepts.

Content

1. MOSFET Operation
2. Simple Transistor Circuits and Current Mirrors
3. Simple OTA & Amplifier Metrics
4. Miller OpAmp
5. OTA Configurations
6. Process Aspects and Noise
7. Layout of Integrated Circuits
8. Digital Circuits
9. Output Stages and Fully-Differential Amplifiers
10. Comparators and Digital-to-Analog-Conversion
The course consists of two parts: After a kickoff meeting and appropriate preparation of the students, five lab sessions consisting of a theoretical and practical part regarding the simulation of integrated circuits are held. Those lab sessions teach the necessary skills to develop integrated analog and mixed-signal circuits by self-employed simulation under professional supervision. Furthermore, the students gather experience and learn to usage of the simulation and development tool cadence virtuoso. After the lab sessions, the students form groups of two and choose a project, which they all by themselves design, simulate and document. Throughout this design process, they are supported by regular meetings and daily contact with supervisors. At the end of the projects, the students generate a data sheet and hold a presentation regarding their developed system, where they can explain and justify their design decisions. Additionally, the supervisor evaluates their simulation results.

Teaching and Learning Methods

During the kickoff meeting, the course script is handed out, which includes a preparation for the students. During the individual chapters, first the theoretical basics are acquired. After that, using Cadence Virtuoso, the individual topics are simulated and designed. After completing all chapters, a prepared project is chosen by the student, which the work on under supervision in groups of two. At the end of the project, the students create a presentation (about 15 min) as well as a datasheet about their project.
