ELECTRICAL SCIENCE II - 2021/2

Module Overview

Expected prior/parallel learning: None

Module purpose: All modern electronic devices make use of transistor technology and their future developments, via Moore’s Law and beyond, are fundamentally linked to device architecture. This module will introduce modern CMOS transistor structures and link to the operation for integrated circuits and modern memory devices. The module will also show how electric and magnetic fields can be unified within Maxwell’s equations to produce electromagnetic theory and solve common problems.

Assessment pattern

Alternative Assessment

Not applicable: students failing a unit of assessment resit the assessment in its original format.

Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes.

The 4 hour open book written examination will assess knowledge of fundamental material properties and their behaviour in electric or magnetic fields; allow the student to demonstrate an ability to perform numerical calculations of key material and device parameters. The assignment will also assess the student’s ability to research into CMOS electronic devices.

Thus, the summative assessment for this module consists of the following a 4 hour open book written examination

Formative assessment and feedback

For the module, students will receive formative assessment/feedback in the following ways.

• During lectures via questions and answers


• During tutorial problem classes


• By means of unassessed tutorial problem sheets (with answers/model solutions)

Module aims

• There are two main aims associated with this module. The first is to introduce transistor structure and to show how the operation and electrical characteristics can be related to both current and future device architectures and material choice. The second aim is to show electromagnetic theory can be applied in radio frequency, high speed digital and microwave engineering and product design at circuit level.There are two main aims associated with this module.

Learning outcomes

Methods of Teaching / Learning

Learning and teaching methods include the following.
Lectures and class discussions

Problem solving classes

Revision sessions  

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
