By Prof. Vančo B. Litovski

Scene 2 (6s)

We will start with the basic materials . You will learn here what semiconductors (and their main representative - silicon ) are and what is their main property. Then, we will explain how these properties are “programmed” to produce the p- and n-type semiconductors.

Scene 3 (24s)

We will talk about the structure making a component to be electronic: the p-n junction. Its i =f(v) [voltage-to-current] characteristic is exponential meaning that it behaves as a switch or rectifier. We will explain the capacitances which are inherent to the p-n junction.

Scene 5 (0s)

Next we will explain what analogue and digital electronics means. For physical realization of both one uses transistors . We will pay much of our attention to the Metal-Oxide-Semiconductor ( MOS ) transistor .

Scene 6 (1m 18s)

The functionality and main applications of most of the existing alternatives will be described e.g. - Bipolar Junction Transistors ( BJT ) - Junction Field Effect Transistors ( JFET ) - High-Electron-Mobility Transistor ( HEMT ) - a nd several others

Scene 7 (1m 36s)

The fundamentals of electronic systems will be introduced. We will explain what is the purpose of the power supply to the electronic circuit. Then we will distinguish the input (receiving a signal) and output (delivering a signal) port of the electronic systems. All these will serve as an introduction to the next course which is “ Basic electronic circuits and signal amplification ”
