General Information

Division: Electrical and Information Technology
Course type: Course given jointly for second and third cycle
The course is also given at second-cycle level with course code: ETIN75
Teaching language: English

Aim

The course is a follow-up to Analog Electronics and gives you deeper insight in design of negative feedback amplifiers. Amplifiers are the core of analogue systems. This is why the theory is applicable to many analogue systems. The course gives a complete design strategy for amplifiers. Several aspects on amplifier design are covered for example noise and frequency compensation methods. The course also touches some control theory.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• •have gained deep understanding of feedback theory
• •be familiar with the transistor’s characteristics and its model in that the student is able to make design choices to optimize noise, bandwidth and bias parameters.

Competences and Skills

For a passing grade the doctoral student must

• •from a given specification be able to design an amplifier that fulfils specifications on noise, bandwidth and bias, by calculating and implementing an ideal amplifier topology using at most three stages.
• •be able to characterize an amplifier using measured data, and suggest and design changes to meet a given specification
• •be well prepared to discuss analogue amplifiers at research level
• •be able to express knowledge in feedback theory orally and in writing.

Course Contents

In this course synthesis of high performance negative feedback amplifiers is presented using a structured design methodology. In order to optimise channel capacity the course covers noise, distortion and bandwidth. Noise: Origin of noise, calculation of input noise source and optimisation of noise performance. Distortion: Origin of distortion, definition of useful figure of merit; Distortion is described by power series and clipping; Optimisation of current budget and effects of local feedback. Bandwidth: Estimation of maximal bandwidth; Phantom-zero and pole-split is used as advanced methods in frequency compensation. Biasing: Biasing of multi-stage amplifiers; Realization of bias sources and global bias feedback.
