Electronics Engineering (Th.) (EE-221)

This subject is intended to provide students with the fundamentals of semiconductor physics and its application to common semiconductor devices. The course starts with an in-depth look at the theory of semiconductors including energy gap, mobility of electrons and holes, influence of temperature on conductivity, doping, photoconductivity, drift and diffusion of charge carriers and the ideal diode equation, diode models. Then, properties of the abrupt p-n junction are studied and applied to various practical devices including the signal diode, zener diode, varactor diode, photo-diode, light-emitting diode, bipolar junction transistor, and finally field effect transistors. Moreover application of diode as rectifier, clipper and clampers are studied in it. BJTs and FETs along with its biasing, types and configurations are studied in detail in the course. The course has a strong laboratory component. About half the experiments illustrate fundamental properties of semiconductor materials and half explore the characteristics and properties of a variety of semiconductor devices.
