### 1. Prerequisites *

- competences corresponding the final attainment level of secondary school

an active knowledge of

- Dutch
- English

Students should master the following basisc mathematical skills:

- Solving systems of linear equations
- Solving a quadratic equation
- Calculate a simple intergral or differential
- Know how to calculate with complex numbers

The physics prerequisites consist of the basic laws of electrostatics and electrodynamics:

- Coulomb's law
- Ampere's law
- Faraday's law
- Ohm's law

Students should have some practical experience with

- building the most elementary electronical networks (parallel and series, power and ground, ...)
- measuring correctly potential differences and currents
- the basic functionalities of a digital multimeter and oscilloscope
- representing measurements numerically and graphically and discuss them in a (self)critical way in a short written report

### 2. Learning outcomes *

- At the end of this course, students will understand the working principles of the most common active and passive analog components.
- At the end of this course, students will be able to use these components in simple electronic circuits.
- At the end of this course, students will be able to measure these circuits and troubleshoot the most common mistakes.
- At the end of this course, students will be capable of using efficiently and correctly the common electronics measurement devices such as the digital multimeter and the digital oscilloscope.
- At the end of this course, students will be capable of deepening their knowledge of analog circuit design and applications by means of self-study.

### 3. Course contents *

The following topics are treated in the oral lectures, for which an English textbook, supplemented with summaries and worked out examples on slides, is used:

Lecture 1:

- Refreshing of basic principles of electronics (laws and passive linear components)

Lecture 2:

- Circuits with passive components: 1st and 2nd order Transients, RL, RC and RLC circuit

Lecture 3:

- The concept of alternating currents, use of complex notation and complex impedance model
- Passive frequency filters: bode plot, phase shifts

Lecture 4:

- The working principles of the semiconductor diode (bipolar junction)
- The bahavior of diodes in circuits,: load line, working point, half and full rectifier
- Special diodes: Zener, Schottky, LED, ...

Lecture 5:

- The working principles of the semiconductor transistor, in particular the MOSFET
- The MOSFET characteristics: transconductance and transresistance, linear model

Lecture 6:

- The use of the MOSFET in practical circuits: amplifiers and switches, active loads
- Frequency analysis of amplifying networks
- Use of MOSFETs in the construction of elementary logic gates

Lecture 7:

- The working principle of an operational amplifier (op-amp) and its equivalent circuit
- Analysis of the inverting and non-inverting op-amp circuit
- The use of op-amps in differential and instrumental amplifiers

The practical labs are obligatory for all course participants. They complement the theory lectures in bi-weekly sessions of 3 hours, in which one or two circuits are studied and measured in detail. One week prior to each lab, students get a few short questions which they should personally prepare before coming to the lab. The answers will be checked during the lab session that follows.

Each lab assignment is carried out in teams of two students and will result in a written report per team. In case of mutual disagreement, students can make a completely personal report and get a personal quote. Reports will be corrected and handed back to the students during the following lab session in order to provide feedback. The quotes of the reports will contribute to half the final examination grade.

### 4 International dimension*

### 5. Teaching method and planned learning activities

Personal work

### 6. Assessment method and criteria

Students need to be present during labs.

Lab exercises cannot be retaken during teh second examination term.

Continuous assessment

### 7. Study material *
