Learning outcomes

The course introduces knowledge required for integrated circuit design, with emphasis on analog circuits. Covered topics include short channel effects, voltage amplifiers, rail-to-rail and CMFB schemes.

After completing the course, students will be able to: (a) discuss the operation of a MOS transistor in weak, moderate, and strong inversion, (b) design voltage and current references, both single and differential input voltage amplifiers, (c) design op-amps with specific gain, speed or switching performance.

Examples will be extensively used to develop students's skills in their ability to analyze and design simple electronic systems.

Course contents

The basic physical behavior and compact modeling for integrated MOSFET transistors. Second order effects.
Basic building blocks of analog integrated circuits: MOS current mirrors and active-load single-stage amplifiers.
Fundamental principles of basic opamp design.
Stability and feedback in electronic systems.
Compensation techniques needed to ensure stability in closed-loop amplifiers. Slew rate, zeroing systematic input offset voltage and process-insensitive lead compensation.
Detailed analysis of the classical two-stage CMOS opamp.
Cascode and fully-differential opamp schemes.
Examples of amplifiers and analog filters circuits.

Teaching methods

Lectures and exercices on topics related to the analysis and design of integrated analog building blocks and operational amplifier.

Detailed examples will be extensively used to develop analytical skills of the students and their capacity to analyze and design simple electronic systems.

Weekly homework will be provided.

Assessment methods

Achievements will be assessed by the means of a final written exam (2hours). No books, laptops, Internet appliances, smart phones, can be used during exams.

In order to properly assess the learning outcomes described above, the examination is composed of two exercices, and the total max score is 30 (min score is 18).

An optional oral session on the topics of the carried out lectures is possible upon request of the student.

To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, and a proper use of technical language.

Higher grades will be awarded to students who demonstrate a firm understanding of the subject and a clear and concise presentation of the contents.

A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.

Teaching tools

Slides, computer simulations examples.
