Electronic Systems and Design (ENGN2218)

ENGN2218 Electrical Systems & Design builds directly on ENGN1218 Introduction to Electrical Systems by developing the students' understanding of the principles and operation of advanced electronic circuits and devices (bipolar junction transistor, operational amplifier, filters, digital logic gates, ADC and DAC, 555 Timer and Instrumentation amplifiers). It also emphasizes the importance of modelling the behaviour of complex electronic circuits and devices using systematic mathematical techniques. PSPICE is used extensively in the analysis and design. Specific topics include:

• Bipolar Junction Transistors: Basic BJT concepts and circuit models, BJT Amplifiers (bias circuits, small-signal and large-signal equivalent circuits), BJT Common Emitter and Common Collector amplifiers, Cascaded BJT amplifiers.
• Op-amp: Op-amp characteristics, closed loop and open loop gains, Schmitt trigger.
• Steady State Sinusoidal Analysis: complex numbers, phasors, impedances, complex power.
• Op-amp Filters: Transfer functions, Bode Plots, First order active filters (low-pass and high pass).
• Digital Electronics: Number systems, Boolean algebra, Logic gates, Combinational logic circuits, Karnaugh maps, Combinational logic circuit design.
• Special topics: Analog to Digital Converters (ADC), Digital to Analog Converters (DAC), 555 Timer, Instrumentation Amplifiers.

## Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. Explain and use engineering abstractions and simple mathematical models to represent non-linear and active circuit elements (such as BJTs and op-amps).
2. Apply circuit analysis techniques in time and phasor domains (such as node-voltage method, mesh current method, Thevenin equivalent circuits, Phasors and complex impedances, Transfer functions, Bode plots) to solve electronic circuits.
3. Analyse and design analogue electronic circuits using BJT and op-amp amplifiers, opamp filters and op-amp comparator circuits.
4. Design combinational logic circuits using digital logic gates and timer circuits using the 555 Timer.
5. Explain in simple terms the working of electronic components and circuits and justify the practical significance of the real world analogue and digital electronic systems considered in the course.
6. Read data sheets and circuit diagrams and recognize building blocks such as power supply, amplifiers, comparators, filters, logic gates, timers and ADC/DAC. Assemble circuits and take measurement of circuit variables using appropriate lab tools (such as oscilloscope, function generator, digital multi-meter, power supply and MOKUs). Simulate circuits using a variety of simulation packages (such as PSPICE, LTSpice, Digitalworks and relevant smartphone app). Compare measurements with simulations.
7. Collaborate effectively with responsibility for personal and group laboratory outputs.

## Other Information

1. All students need to purchase a lab kit (breadboard, wire kit, components) for around \$30. The online payment link and pickup instructions are posted in wattle.
2. This course makes heavy use of the associated Mastering Engineering for Hambly textbook.
3. To pass this course, students need to attend and complete at least 6 out of the 7 Labs.

## Indicative Assessment

1. Mastering (5 online assignments) (10) [LO 1,2,3,4,5]
2. Labs (7 integrated computer and hardware labs) (30) [LO 1,2,3,4,5,6,7]
3. Mid-semester Exam (20) [LO 1,2,3,5]
4. Final exam (40) [LO 1,2,3,4,5]

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.

• A nominal workload of approximately 12 hours/week including the following: 2 x 2hr lectures/week, 25 x 10-20min online lectures, 7 x (3hr or 4hr) laboratories, 5 x online Mastering tutorials (1-3 hours each) and 8 self study problem sets (1-3 hours each).
• Weekly average contact hours will be 8 hours (2 x 2 hour lectures and a 4 hour laboratory).
• Expected non-contact (self) study hours are 3-5 hours/week.
