ANALOGUE CIRCUITS | ESSF01 |

**Aim**

The course is the starting point of the path towards design and development of analogue circuits like amplifiers, oscillators, mixers, AD-converters etc. It is the base for the courses Advanced Analogue Design, Analogue IC-design and Radio electronics. Further the course is useful for the project courses Analogue Projects and IC Projects.

Knowledge in linear systems and semiconductor physics are used. The course also presents interesting applications within control theory.

*Knowledge and understanding*

For a passing grade the student must

- Gained general understanding in feedback theory and the benefits of negative feedback amplifiers to the extent that it is possible to select an amplifier topology and be able to determine how the ideal parameters will degrade when implemented using real components.
- Be familiar with the transistor and the different transistor stages and their characteristics, and thereby be able to decide what stages a multi-stage implementation needs to meet a given specification.
- Be familiar with the frequency dependence of active and passive components and master methods for bandwidth estimation and frequency compensation, to achieve desired frequency behaviour.
- Be familiar with the characteristics of a good oscillator and be able to present an example of one.

*Skills and abilities*

For a passing grade the student must

- From a given specification be able to design an amplifier that fulfils specifications on bandwidth, step response and accuracy, by calculating and implementing an ideal amplifier topology using at most three stages.
- Be able to make a frequency and time domain analysis of a circuit from a set of measured values and a schematic.

*Judgement and approach*

For a passing grade the student must

- Be able to describe and discuss feedback theory applied on analogue building blocks in negative feedback amplifiers.

**Contents**

Amplifiers are used in many areas for example in mobile phones, signal conditioning, medicine equipment and in computers. The course gives a systematic method with which an optimal amplifier may be designed. The course (for students of Electrical Engineering) prepairs the student for a project, described in ESSF05 Project in Electronics and Sustainable Development
