Industrial Electronics

Characteristics of the ideal operational amplifier and real-world deviation (impact of final gain, input and output resistance, current, offset voltage, attenuation of common mode voltage); Study of basic linear and nonlinear circuits with an operational amplifier (adder, subtractor, integrator, differential, logarithmic and exponential amplifier, multiplier); Equivalent circuits and mathematical models of circuits for DC steady-state and small-signal changes; Overview, derivation of mathematical models, sensitivity analysis in the case of selected circuits of measuring and control technology (current / voltage and voltage / current converter, operational amplifier circuits, instrumentation amplifier, peak and effective value measurement, precision half-wave and full-wave rectifier, serial and parallel voltage stabilizer circuit, controllers (P,I,PID), voltage limiters).

The objective of the course is to provide the student with knowledge in the field of signal processing circuits based on an operational amplifier. The subject includes technical challenges from various technical fields (measuring, process and controlling technique). It provides theoretical bases for the analysis and assessment of the deviations caused by the properties of the real components. It provides knowledge about the constraints of such components and circuits that are formed by real components.

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 learn about components, their real properties and their role in various basic circuits. 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.
