ELEC40002 (ELEC40002) Analysis and Design of Circuits


Lecturer(s): Prof Andrew Holmes; Prof Paul Mitcheson

Aims

This module provides a foundation in the analysis and design of electronic circuits, introducing key concepts that are essential for higher level study of electronics. You will become familiar with the behaviour of the core electronic components that form the building blocks of all electronic systems. You will also learn how to analyse circuits constructed from these components in order to establish how the voltages and currents at different points are related. This will include both time-domain and frequency domain analysis, and the method of small-signal analysis for handling non-linear components. In the course of the module you will become familiar with a range of standard circuit blocks and gain an appreciation of how these are applied in real world applications.

Learning Outcomes

Upon successful completion of this module you will be able to:
1. Explain the basic physics underlying the operation of the following electronic components: resistor, capacitor, inductor, diode, transistor;
2. Perform DC analysis of circuits containing combinations of the above components to establish the nodal voltages and branch currents;
3. Perform AC analysis of circuits containing combinations of the above components, using small-signal equivalent models to linearise any non-linear elements;
4. Apply the operation of simple transistor level circuits including amplifier stages and logic gates;
5. Analyse basic opamp circuits containing idealised opamps and passive components;
6. Apply the concept of a transfer function and derive the transfer functions for a range of standard filter circuits;
7. Analyse the transient behaviour of 1st order RC and RL networks;
8. Use SPICE to simulate the behaviour of the circuits you have studied;
9. Appreciate where and how the circuits you have studied are applied in real engineering applications.
