History and overview of electronics from vacuum tubes to large scale integration, including
reasons for studying electronics, selected important areas of application, role of electronics in
computer engineering. Semiconductivity: materials and properties, electrons and holes, concept of
doping, acceptors and donors, p and n-type materials, conductivity and resistivity. Diodes and
Circuits: symbol and representation, diode operation and characteristics, region of operation and
limitations, zener and schottky diodes, diode circuit and load line, diode application in rectifier
and dc/dc converter, diode logic functions - AND and OR . Bipolar Junction Transistors (BJT):
physical structure of BJT, symbol and circuit representation, NPN and PNP transistor operation,
voltage-current characteristics of transistors, transistor region of operation and limitation,
transistor circuit analysis, biasing for logic application, transistor operation as logic functions –
OR and AND logics.
