Aims

The aims of the course are to:

• Teach students how electrical and electronic circuits are analysed, how field effect transistors and amplifiers operate, how real and reactive power flows in a.c. circuits, and to teach basic transformer theory.

Objectives

As specific objectives, by the end of the course students should be able to:

• Ohm's law, ideal voltage and current sources, Thevenin and Norton theorems and Kirchhoff's laws in DC circuit analsys (Lectures 1-2)
• Power is transferred from a source to a load and how any network can be represented by a Thevenin or a Norton source.(Lecture 3).
• Complex numbers in the analysis of AC circuits leading to impedance. Resonance, Q-factor in electronic circuits.(Lectures 4-5).
• Analyse AC circuits including gain, frequency response, and impedances of AC circuits.(Lectures 6).
• Introduce the amplifier model to determine gain, input and output impedance. Bode plots and frequency response (7-8)
• Understand how doped semiconductors can produce p-type and n-type, introduce the p-n junction diode. (Lecture 9)
• Know the principles of operation of the Metal Oxide Semiconductor Field Effect Transistor (MOSFET).(Lecture 10)
• Know how an equivalent circuit for a MOSFET can be used to determine the small-signal performance of the circuits.(Lectures 11-13).
• Introduction to ideal operational amplifiers (Op Amps) and exampoles of useful (Lectures 14-26).
• The concepts of real, reactive and apparent power, and power factor, power factor correction of AC loads (FU Lectures 1-2)
• The principles of the transformer, and the development and use of its equivalent circuit. (FU Lectures 3-4)
