Subject description


  • The entry requirements are specified by the Faculty of Electrical Engineering.
  • To attend the written exam, the candidate has to complete laboratory work and write the associated reports.

Content (Syllabus outline):

  1. Passive components: resistor, thermistor, varistor, capacitor and choke: U/I and other static characteristics. Dynamic and thermal constraints. Criteria for sizing and selection of passive components.
  2. Properties and characteristics of semiconductor diodes, bipolar and unipolar transistors. Equivalent circuits and mathematical representation of semiconductor components for DC conditions and small signal analysis.
  3. Operational amplifier. Characteristics of an ideal operational amplifier and the deviations of the real: the impact of the frequency bandwidth, input and output resistance, the bias current, offset voltage, common mode attenuation. The basic linear and nonlinear operational amplifier circuits: adder, subtractor, integrator, differentiator, logarithmic and exponential amplifier, multiplier. Important circuits for measurement and control techniques (current/voltage and voltage/current converter), bridge circuits with operational amplifier, instrumentation amplifier, peak and effective values meter, precision half-wave and full-wave rectifier, reference circuits, controllers, limiters and voltage limiter). Active filters. Switching circuits with and without switching hysteresis and function generators. Series and parallel circuit voltage stabilizer.

Objectives and competences:

To provide basic understanding of the operation, selection and dimensioning of passive electronic components and semiconductor in the case of basic and more complex circuits in the fields of measurement and control techniques.

Acquaintance with the characteristics of real electronic components and circuits is the basis for critical assessment of the whole mechatronic system and identification of possible errors and deviations.

Intended learning outcomes:

Understanding the operation and physical limitations of passive and active analogue and digital components. To gain deeper knowledge during the analysis and design steps in problem solving of partial and complex circuits. Knowledge of specific circuits and signal processing in the field of measurement and closed-loop control techniques. Understanding and application of learned principles in the identification and analysis of the components discussed in simple as well as complex circuits.

Learning and teaching methods:

  • Classical lectures with a number of practical tutorial examples.
  • Encouragement of individual study in the form of homeworks.
  • Laboratory work for practical verification of lecture material.
