Unit description Unit description
This unit builds on ELEC2070 and introduces non-linear and active circuit elements in theory and in the laboratory. The goal is to understand and apply simple electronic design to active circuits such as amplifiers, wave shaping circuits, rectifiers etc. It consists of 4 modules: operational amplifiers, diodes, BJTs and MOSFETs. The operational principles of each device are discussed and applied to circuit design. Models for circuit analysis are presented for each device including large and small signal analysis. Computer simulation and analysis of simple circuits is introduced and used in the laboratory. Laboratory sessions also include building and testing circuits and subsequent formal report writing.

Important Academic Dates

General Assessment Information

Notifications

Formal notification of assessment tasks, grading rubrics and due dates will be posted on iLearn. Although all reasonable measures to ensure the information is accurate, The University reserves the right to make changes without notice. Each student is responsible for checking iLearn for changes and updates.

Weekly Plan

A weekly plan of lectures, assignments, tests, laboratory and workshop sessions will be posted on iLearn. Students are expected to consult it and be aware of possible minor variations.

There will be no laboratory or tutorial session in week 1.

Assignment Tasks

Assignment questions will be posted on iLearn at least one week before their submission date.

Assignments will be in the form of iLearn quizzes and must be completed and electronically submitted prior to their due date.  Correct answers and feedback will be provided within weeks of the submission due date.

All assignments should be prepared individually. It is expected that students consult tutors, lecturers or other students while learning the concepts, but copying assignments from others is not accepted. Students are expected to have read and understood the academic honesty policy.

Assignment questions will come from a question bank and in some cases have variable numbers. Whilst all students will face similar questions, the numerical details and therefore the correct solution will vary.

Absences

Late notices or absences from tests, workshops and laboratories will be considered under extenuating circumstances upon lodgement and approval of a formal notice of disruption of studies.

Grading

In order to pass this unit a student must obtain a mark of 50 or more overall or obtain a passing grade P/ CR/ D/ HD.  For further details about grading, please refer below in the policies and procedures section.

Late submissions & Special Consideration

Late submissions of assignment or lab reports will not be allowed unless a formal disruption of studies has been submitted. 

If you receive special consideration for the final exam, a supplementary exam will be scheduled by the faculty during a supplementary exam period, typically about 3 to 4 weeks after the normal exam period. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.

Changes from Previous Offering

Weekly lecture time has been reduced from 2 hours to 1 hours, and is now supplemented by additional original online learning content which is also posted weekly. The simulation software used throughout this unit has been changed from AWR to LTspice.  Laboratory exercises have been updated so they can be carried out using Analog Discovery portable electronics lab kits, enabling more flexibility in how students can approach the practical learning elements of this unit.

Changes in Response to Student Feedback

The simulation software used throughout this unit has been changed from AWR to LTspice after student feedback from previous offerings noted the steep learning curve and non-intuitive interface of AWR. LTspice also has the advantage of having no licence restrictions.
