ELECTRICAL SCIENCE II - 2023/4

Module Overview

 

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 Strategy

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

The open book written examination will assess knowledge of fundamental material properties and their behaviour in electric or magnetic fields; allowing 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:

• an open book written examination.

• During lectures via questions and answers


• During tutorial problem classes


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

Module aims

• This module builds upon EEE1034 Electrical Science I which introduces students to electronic materials and transistors (part A) to fields and charges (part B). There are two main aims associated with this module. The first is to how the structure and architecture of modern energy efficient transistors influences their operation and electrical characteristics. 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.
• Part A of the module feeds into Semiconductor Devices and Optoelectronics (EEE3041) and part B into rf and microwave fundamentals (EEE3032).
• The module also aims to provide opportunities for students to learn about the Surrey Pillars listed below.

Learning outcomes

Methods of Teaching / Learning

Learning and teaching methods include the following.
The methods of learning at teaching in this module reflect the strong functional design component in part A and the extensive use of mathematical concepts in Part B.  As such the approach to learning and teaching is to

(i) provide extensive in-class sessions of lectures to provide students opportunities to learn about design concepts of modern devices

(ii) provide in-class lectures and online resources showing the mathematical development of proofs of important concepts

(iii) Problem solving classes with previously released problems allowing students to master their ability at device and other calculations; model solutions will be released via SurreyLearn.

(iv) Opportunities for in-class discussions of the topic taught

(v) Revision sessions of problem sheets and past examination papers

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.

Other information

Energy efficiency is at the heart of modern electronic devices and this module will introduce students to sustainable electronic devices with user design requirements; this is aligned to UNSDG no. 7. The module provides ample opportunity for students to demonstrate their mastery of design and calculations which will aid the student’s employability. Students’ resourcefulness and resilience will be enhanced as the they will need to think critically and exercise engineering judgment of some of the underlying assumptions they would need to employ in advanced calculations.
