PHY3026 : Electronic Devices

Semesters
Semester 1 Credit Value: 10
ECTS Credits: 5.0

Aims

To provide to specialist knowledge of electronic devices. To enable students to have a better
understanding of state-of-the-art devices (e.g. transistors). To enable students to compare competing
electronic technologies.

Teaching Rationale And Relationship

Lectures provide core material and guidance for further reading. Problem solving is introduced through lectures and practiced during private study.

Problems on each section of the syllabus are the most vital component of learning and understanding the materials covered in lectures and constitute the primary vehicle for student learning.

In addition office hours (two per week) will provide an opportunity for more direct contact between individual students and the lecturer: a typical student might spend a total of one or two hours over the course of the module, either individually or as part of a group.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The examination provides the opportunity for the student to demonstrate their understanding of the course material. The problem solving aspects of the examination enable the student to demonstrate that they are able to apply this understanding and their analysis and synthesis to novel situations.
