Analog and Digital Electronics

Subject description

Introduction to passive components: resistor, thermistor, varistor, capacitor and inductor (U / I and other static characteristics, dynamic and thermal constraints, norms for dimensioning / selecting passive components); Introduction to and construction of equivalent models of components; Treatment of semiconductor materials (covalent bond, doping, diffusion, recombination) and components (characteristics of diodes, bipolar in a unipolar transistor); Introduction to the operational amplifier; Characteristics of the ideal operational amplifier (basic linear in nonlinear circuits with operational amplifiers); Introduction to basic logic gates and their constraints (voltage levels, load, switching times); Introduction to basic circuits in the field of power electronics (rectifier, reference generators, basic circuits for signal processing) and evaluation of their functionality (sensitivity analysis); Overview of discrete sensors for non-electrical quantities (static and dynamic properties, sensor selection criteria, practical examples of design and dimensioning of sensor systems).

The subject is taught in programs

Objectives and competences

The objective of the course is to provide the student with knowledge about discrete and integrated, linear and nonlinear components; Rounding up knowledge in the direction of linking individual components into larger systems; The focus is on practical examples of the analysis and dimensioning of basic and more complex circuits that occur in mechatronic devices.

Teaching and learning methods

The lectures give the theoretical basics of the discussed chapters together with the presentation of the process of solving simpler practical challenges. Students are provided with detailed study material. Practical work is carried out within laboratory exercises, where students gradually become acquainted with different components. They also learn about measuring instruments and the most common hazards and measurement errors.

Laboratory models allow the simultaneous work of two or three students who report the final results at the end of the semester by comparing the results from the literature.

Expected study results

After successful completion of the course, students should be able to:

– describe the physical structure of the components and the operation of the discussed circuits,

– develop an equivalent model of components and of the discussed circuits,

– implement the presented analytical procedures in the simpler and more complex circuits,

– calculate the current, voltage and power stress of the performing components,

– explain the physical and technological backgrounds that manifest themselves in the deviation of the properties of real components from ideal ones,

– design more complex circuits in the field of measurement, process and control regulation techniques.
