Basically all engineering systems have one or several important parts which may be classified as electronics, some systems are even completely electronic. In particular, most measurement situations are centred round the conversion of a physical quantity to an electric signal. This has brought about a world wide industry and labour market, and most engineers are assumed to have basic knowledge of electronics.

This course is a basic course on modelling of electronic systems. In particular, the modelling chain 1) determine circuit models for the physical processes in various components such as resistors, transistors etc, 2) perform mathematical analysis of the circuit model, and 3) interpret the results as system parameters such as loss and amplification.

Knowledge and understanding

For a passing grade the student must

- be able to use terms such as electric and magnetic fields, current, voltage, power, impedance, transfer function, amplification, and bandwidth, to describe and discuss ideas, problems and solutions regarding basic components and simple electronic systems for people with professional knowledge of electromagnetics and electronics.

Competences and skills

For a passing grade the student must

- be able to construct circuit models for simple electronic systems.
- be able to calculate resistance and capacitance for given geometries.
- be able to analyse given linear and nonlinear circuits with a small number of nodes by hand.
- be able to design circuits which attain given specifications, for instance simple passive filters and amplifiers.

Judgement and approach

For a passing grade the student must

- for an electrical system problem, be able to choose level of modelling and method of analysis in order to answer the question adequately.

The course consists of circuit theory, electromagnetic field theory, and electronics. In the circuit theory and the field theory part, basic tools of analysis, physical components, and their ideal circuit models are treated. The circuit theory is then used in the electronics part to study semiconductor components and electronic systems.

Basic electric quantities: Current, voltage, potential, resistance, conductivity, permittivity, impedance, admittance, and power.

Basic analysis tools: Maxwell's equations, electrostatics, magnetostatics, boundary conditions, Kirchhoff's laws, calculational methods for linear, time invariant circuits, node analysis, and two-terminal equivalents.

Basic components: Resistors, inductors, capacitors, voltage sources, current sources, amplifiers, and transmission lines. Modelling: Physical circuits with ideal circuit elements, transfer functions, and filters.

Semiconductor components and electronic systems: operational amplifiers, amplifier circuits, diodes, transistors, integrated circuits, and digital systems.

Grading scale: TH

Assessment: Written exam. Non-compulsory home assignments may give bonus points to the written exam.

Required prior knowledge: For N: FMFF20 Mathematical Methods of Nanotechnology. For F: FMAF05 Mathematics - Systems and Transforms. For BME: concurrent participation in ETI265 Signal Processing in Multimedia.

The number of participants is limited to: No
