Programme
Basic analog transistor circuits. Basic single transistor amplifier stages. Small signal equivalent circuits of the basic single-stage amplifiers. Common base (gate), common emitter (source), common collector (drain) amplifier stages. Degenerate common emitter (source) stages; analysis and features. Frequency response of the amplifiers. High frequency small signal models, the Miller-effect. Low frequency analysis of the transistor circuits. Biasing of active devices. Current mirror. Maximum output signal analysis of the transistor circuits. Power amplifiers; A, AB, B, C, AD and BD power stages. Two-transistor basic amplifiers. Differential amplifier, cascade stage. Differential amplifier: large signal analysis and transfer characteristics; incremental analysis and half-circuit analysis techniques. Nonlinear distortion of the transistor stages. Harmonic and cross modulation distortion. Ideal operational amplifier, basic circuits. Structure of the operational amplifiers. The effect of the feedback to the small signal parameters. Frequency compensation of the feedback amplifiers. Comparator circuits. Sample and hold circuits. D/A and A/D converters. Schmitt trigger, monostabil multivibrator. Oscillators, square-wave relaxation oscillator, astabil multivibrator, sinusoid RC and LC oscillators, crystal oscillators. Basic elements of the digital electronic circuits. Parameters of the digital inverter: logic levels, delay time, etc. The transfer characteristics of the digital inverter, threshold level. The CMOS logic circuits. Basic CMOS inverter, W/L ratio, transfer characteristics. Dynamic behavior of the CMOS circuits. The structure of the CMOC gates.
Virtually every electronic equipment used today is constructed on the basis of high complexity circuits. All electrical engineers must know the construction and functioning principles of such devices. In order to understand the behavior of complex systems, the elementary design principles and dimensioning procedures should be presented which is the objective of this course.
Obtained skills and expertise:
The students get acquainted with the definitions and management of the parameters of electrical components and will understand the calculations of the properties of electronic circuits built up of such components. The skills obtained in the framework of this course (together with the course entitled Electronics 2) empowers students with the necessary expertise to understand the courses of the related study specialization blocks.
