The necessary condition of the successful termination of the subject is the successful pass through the examination, i.e. the marking of the examination by the "výborně", "velmi dobře" or "dobře" mark. The examination must be performed within the time period prescribed by the time schedule (harmonogram) of the academic year that corresponds to the date of the subject registration.

Operational amplifiers Basic applications of ideal operational amplifiers (inverting and non-inverting amplifier, summation and integration of analog signals). Real operational amplifier (bias input current, slew rate, frequency and phase characteristics). Stability criteria, back-loop effect. Comparators, Schmidt triggers. 3. Principles of semiconductor elements Physical principles of diodes, bi-polar and uni-polar transistors, and other semiconductor elements. Characteristics of diodes and their applications (rectifiers, filters, switching circuits). 4. Amplifiers, feed-back loop Working point, working line, common base, emitter and collector circuits. Single-stage and multi-stage amplifiers, inter-stage coupling, frequency response. Amplifier classifications (broad-band, selective, AC, DC, impulse, power amplifiers). Feed-back loop in amplifiers, its influence on amplifier characteristics. 5. Analog control and regulation Principles, P, PI, PID regulators. Linear and switching voltage stabilizers. DC-DC converters, HV converters. 6. Optoelectronic elements and their application Photoresistor, photodiode, phototransistor - functional principles, examples of applications. LED diodes, opto-couplers, examples of analog circuits with optical coupling. 7. Signal generators Harmonic generators with LC and RC circuits, crystal controlled oscillators. Generators of non-harmonic signals (triangle, saw-tooth, square wave), flip-flop triggers. 8. Modulation and signal mixing Modulation classification (amplitude, frequency, phase). Demodulation. Analog radio and TV broadcasting.
The lecture is complemented by a practical exercise in the extent 0/1. The exercise is carried out in the form of completing four practical tasks, which in turn familiarize the listeners with (i) the basic properties of DA and AD converters, (ii) the properties of DA and AD converters of the sigma-delta type with a resolution of 16-24 bits, (iii) the basics of microwave measurements in the 10 GHz band and (iv) with measurements of sheet resistance and electron mobility in a thin layer by the Van der Pauw method.
