Timing and Structure

Weeks 3-8 Michaelmas term and weeks 1-3 Lent term. 22 lectures, (18 on linear circuits (CD), 4 on power flow (FU), 2 lectures/week, in Michaelmas term, 3/week in Lent term.

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:

  • Know how Ohm's law, the concepts of ideal voltage and current sources, and Thevenin's and Norton's theorems are used by electrical engineers to calculate currents and voltages in d.c. and a.c. circuits. To explain Kirchhoff's voltage and current laws and
  • Know how power is transferred from a source to a load and how any network can be represented by a Thevenin or a Norton source.(Lecture 4).
  • Understand how semiconductors can be doped to produce p-type and n-type semiconductors, introduce the p-n junction diode. (Lectures 5 & 6).
  • Know the principles of operation of the Field Effect Transistor (FET).(Lectures 6 - 8)
  • Use complex numbers in the analysis of a.c. circuits and keep track of amplitude and phase simultaneously. Understand the importance of resonance and resonant frequency in electronic circuits.(Lectures 9-12).
  • Know how an equivalent circuit for an FET can be used in transistor circuits to determine the small-signal performance of the circuits.(Lectures 13-14).
  • Calculate the gain, frequency response, and input and output impedances of amplifier circuits.(Lectures 15-16).
  • Introduction to operational amplifiers (Op Amps), and understand how feedback can be used in amplifier circuits to improve frequency response, gain stability and output and input impedances. (Lectures 17-18).
  • Understand the concepts of real, reactive and apparent power, and power factor, the importance of power factor correction of a.c. loads, the principles of operation of the transformer, and the development and use of its equivalent circuit.
