Unit description
This unit considers frequency dependence and active circuit elements. It develops the concepts of time-domain versus frequency-domain analysis, and Bode plots. For active elements, the unit introduces diodes and transistors, analysis of amplifier circuits, operational-amplifier-based active filters, and oscillators.

General Assessment Information
Students need to get a pass mark on each of the assessment tasks to pass the unit.
Assessment Tasks
| Name | Weighting | Due |
|---|---|---|
| Laboratory participation | 15% | Weekly (see iLearn) |
| Laboratory reports | 15% | Four-weekly (see iLearn) |
| Assignments | 20% | Two-weekly (see iLearn) |
| Exam | 50% | Will appear in exam calendar |
Laboratory participation
Due: Weekly (see iLearn)
Weighting: 15%
Laboratory sessions start in Week 2. They are compulsory for all students. There will be both practical sessions and tutorials. All laboratory sessions are based on learning outcomes and students are required to review the concepts introduced in lectures before coming to each laboratory session. They will be given a quiz before the laboratory session to test their level of preparation.
Each student must have one bound notebook to be used as a laboratory/tutorial log (A4 size preferred, graph pages are not required). This logbook should also be used for any preliminary work. It should contain dates, calculations and results recorded during these sessions and student’s comments in time order. On the completion of each session, logbook entries must be signed and dated by a tutor. At the end of the semester the logbooks will be collected for final marking.
Food and drink are not permitted in the laboratory. Students will not be permitted to enter the laboratory without appropriate footwear. Thongs and sandals are not acceptable.
On successful completion you will be able to:
- Extract ac circuit equivalents of two-port networks to determine power transfer
- Apply trans-dependence concept to model amplifiers and transformers
- Apply dynamic-resistance concept to nonlinear elements to simplify their large-signal models into linear small-signal models
- Use correct engineering techniques in measurements, circuit construction, analysis and reporting
Laboratory reports
Due: Four-weekly (see iLearn)
Weighting: 15%
Students will prepare individual laboratory reports summarising their practical work. A typical engineering-journal format will be used. There will be 3 reports, one for each learning-outcome module. Reports will be submitted electronically through iLearn.
On successful completion you will be able to:
- Use correct engineering techniques in measurements, circuit construction, analysis and reporting
Assignments
Due: Two-weekly (see iLearn)
Weighting: 20%
Assignments will be based on the key concepts being introduced at each learning-outcome-module (two assignments for each module). Assignment questions will be posted on iLearn one week before their due date. Submissions will be hand-written or electronic (check iLearn).
All assignments should be prepared individually. It is expected that students consult staff or other students while learning the concepts, but copying assignments from others is not acceptable.
On successful completion you will be able to:
- Extract ac circuit equivalents of two-port networks to determine power transfer
- Apply trans-dependence concept to model amplifiers and transformers
- Apply dynamic-resistance concept to nonlinear elements to simplify their large-signal models into linear small-signal models
Exam
Due: Will appear in exam calendar
Weighting: 50%
The final exam will be closed-book and 3 hours. A formula sheet will be provided if necessary
On successful completion you will be able to:
- Extract ac circuit equivalents of two-port networks to determine power transfer
- Apply trans-dependence concept to model amplifiers and transformers
- Apply dynamic-resistance concept to nonlinear elements to simplify their large-signal models into linear small-signal models
Delivery and Resources
Text Books:
- Svoboda & Dorf "Introduction to Electric Circuits", Wiley, 9th or 8th Editions, electronic or printed versions.
- Sedra/Smith "Microelectronic Circuits", Oxford University Press, International Sixth Edition
Required unit materials:
- Text book
- Lecture notes and notes for practical sessions (available from iLearn)
- Bound logbook for all practical sessions
Technology used:
Practical use of electronic equipment such as oscilloscopes, spectrum analysers, ac and dc sources will be employed during laboratory sessions. Soldering of electronic components will be introduced. Students will construct and measure practical circuits relevant to learning outcomes.
New circuit simulation software (AWR Microwave Office) will be introduced for steady-state frequency-domain analysis. Other software already familiar to students such as MATLAB, and typesetting software such as Latex may be used.
Unit Schedule
The unit is composed of three modules. Each module will run for four weeks and be directly linked to the learning outcomes. Each module will include weekly lectures, weekly laboratory sessions, two assignments and one laboratory report.
A detailed weekly schedule will be posted on iLearn.
