This module aims to equip students with a thorough understanding of diodes and transistors by exploring the underlying behaviour, key properties, and equivalent circuit models, while also highlighting their broad range of practical applications. Building on this foundational knowledge, students will develop the competence to create and evaluate simple rectifier and stabilizer circuits, justifying their design decisions through clear, logical reasoning. The module further enables students to design, construct, and critically assess basic BJT and MOSFET circuits, such as biasing networks and those requiring both DC and AC analysis, with particular attention to key performance parameters, including input/output resistance, power gain, voltage gain, and current gain. Finally, students will gain practical experience conducting detailed frequency response analyses of amplifier circuits, taking into account the effects of coupling and bypass capacitors.
A. Explain the behaviour, important properties, and equivalent circuit representations, and identify various applications of diodes and transistors. B. Create and evaluate simple rectifier and stabilizer circuits, providing detailed reasoning for chosen designs. C. Design, construct, and critically assess simple BJT/MOSFET circuits (e.g. biasing circuit, DC analysis, AC analysis) with regards to input/output resistance, power gain, voltage gain, and current gain. D. Perform detailed frequency response analysis of simple BJT/MOSFET amplifier circuits, considering the impact of coupling and bypass capacitors.
The teaching and learning approach for this module is centred on the lectures, hands-on laboratory work, and guided problem-solving tutorials to foster both theoretical understanding and practical competence. Lectures will introduce and clarify the core concepts related to semiconductors, diodes, and transistors, including their properties, equivalent circuit models, and applications. This will be achieved through the use of worked examples, demonstrations, and visual aids, which will reinforce key ideas and encourage engagement. Throughout the module, students will participate in laboratory classes designed to provide experiential learning opportunities, where they will create, test, and evaluate simple rectifier, stabilizer, and amplifier circuits. These sessions enable students to apply theoretical knowledge to real-world electronic problems, develop their skills in circuit construction and measurement, and critically assess circuit behaviour under different conditions. Problem-solving tutorials will support students in developing their analytical abilities, offering a space to work through circuit design challenges, interpret experimental results, and receive feedback from both peers and instructors. Learning resources, including lecture notes, worked solutions, and simulation tools, will be made readily available. Academic support will be provided through scheduled office hours and online discussion forums.
