Principles and Applications of Electronic Devices and Circuits

Aim and purpose

This unit aims to give learners an understanding of electronic devices and the skills needed to simulate, construct and test a variety of electronic circuits. Unit introduction Electronics and electronic devices are used in a huge variety of manufactured products. From everyday popular items such as cameras and thermometers to the robotic welding machines used in industry, the use of electronics is continually  growing.

This unit provides a practical introduction to basic electronic devices and analogue and digital electronic principles. It provides learners with an opportunity to investigate the operation of diodes and  transistors, two of the most important building blocks in electronic circuits. Learners will then go on to build and test circuits that make use of these devices and will consider the operation of integrated circuits such as the operational amplifier. Logic gates and flip-flops are also investigated both in practice and by using simple electronic principles, such as voltage gain or truth tables.

Finally, the unit will introduce learners to computer-based circuit design and simulation software packages that will allow them to build and test analogue and digital circuits. This will enable learners to recognise the importance of simulation software in the design of electronic circuits.

The overall aim of this unit is to build learners’ confidence in their ability to construct and test simple electronic circuits. The emphasis is on prototyping, constructing and measuring. The unit treats systems in  terms of their functionality and their input/output relationships.

Learning outcomes

On completion of this unit a learner should:
1 Understand the function and operation of diodes, transistors and logic gates
2 Be able to build and test operational amplifier-based analogue circuits
3 Be able to build and test combinational and sequential logic circuits
4 Be able to use computer-based simulation software packages to construct and test the operation of analogue and digital circuits.
