Module description

The module incorporates two major themes: The first is the circuit orientated theme aiming to engender both an intuitive understanding of simple circuit design and functionality.

The second focuses on the more formal analysis and computer simulation techniques using equivalent circuit transistor models where key skills in numeracy and circuit simulation are developed and then used in the design, simulation and construction of oscillator circuits. The module is supported by laboratory-based assignments that investigate small signal amplifiers, and voltage-controlled oscillator design and applications.

Module aims

This module aims to develop an in-depth understanding of analogue systems and circuit techniques from a design process perspective.


Module learning outcomes

On completion of this module, students will be expected to be able to:

1. Derive ac-equivalent models from transistor terminal behaviour as an aid to small-signal analysis and as a design aid for small-signal audio amplifiers and linear oscillators.

2. Understand the design process and system requirements and apply these in the design of single-stage transistor amplifiers, basic operational amplifier circuits, and power supplies.

3. Use CAD tools such as MultiSIM to perform circuit-level simulations.

4. Implement, test and evaluate practical design solutions and communicate the methodology, results and conclusions in both written and oral form.

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
