Course type: Course given jointly for second and third cycle
The course is also given at second-cycle level with course code: ETIN25
Teaching language: English

Aim

The aim of the course is to give understanding and knowledge for the students to be able to construct their own analogue cricuits. Analogue IC Design builds upon the knowledge obtained in the courses Analogue Circuits and Advanced Analogue Design, where amplifier design using discrete components has been taught. The topic of Analogue IC Design is design of amplifiers on integrated circuits, with the aim of creating a solid understanding of analogue integrated circuit design. The focus is on CMOS technology, which is the most common technology for integrated circuits. The aim of the laboratory part of the course is to create skills using CAD-tools for IC-design, so that the students after completing the course can perform an analog IC-project.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• know how a CMOS circuit is built up, how the designer can control the shape of the circuit using the layout, and how different components such as transistors, diodes, resistors, and capacitors can be realized.
• be able to describe the behaviour of the MOS transistor and other components, for small signals as well as large. Furthermore be able to describe the function and characterizing properties of different building blocks designed using these components. Examples of such building blocks are current mirrors, amplifier stages, and operational amplifiers.
• be able to describe how CAD-tools are used in the design of analogue integrated circuits.

Competences and Skills

For a passing grade the doctoral student must

• be able to choose a suitable circuit topology for a given specification and to choose the parameters of the components involved such that the specification is met, and be able to analyse a given circuit regarding its function and performance. Furthermore be able to design and analyze the layout of components and calculate their desired parts as well as their parasitics.
• be able to simulate analogue integrated circuits, design their layout, and verify the layout using CAD-tools.
• have achieved sufficient basic knowledge and learnt the most common terms, so that he/she can discuss ideas, problems and solutions with people active in the analogue IC design field.

Judgement and Approach

For a passing grade the doctoral student must be able to judge if a design is suitable for integration on a CMOS chip or not.

Course Contents

The course starts with a short part about how CMOS circuits are manufactured, and how the designer can control the shape of the circuit using the layout. Then the realization of different components and their properties are covered. An emphasis is put on equations and models that describe the behaviour of the components, especially the MOS transistor. The components are then combined to different building blocks, primarily current mirrors, amplifier stages, and operational amplifiers. The choice of circuit topology and component parameters to meet a given specification is a very central part of the course, as well as analysis of given designs. Modern CAD-tools for analogue IC-design is also an important part of the course, where the laboratory work is central. It covers design and simulation on schematic level as well as on layout level. After completed course one should be able to perform an IC-project (ETIN01) with analogue orientation. One can also continue with design of radio frequency CMOS circuits in Integrated Radio Electronics (ETI170).
