Electronics Applications Project
Major Design Project
1. Design a circuit or system chosen from the list below. You must register your choice with your teacher as soon as possible, and stay with your chosen circuit or system to completion, unless there are exceptional circumstances demonstrated through the simulation and testing, and your teacher approves the change. You will be required to provide to your teacher regular status reports that detail your progress, any problems you’ve encountered, the assistance you have sought, and the solutions to the problems you have tried. These status reports must be both in person and in writing.
2. Create a simulation of the circuit you have chosen using the student addition of P-Spice or Lab-View, and use the P-Spice/Lab-View probes to show the full DC conditions in the circuit, and to show the input and output voltages for the circuit. The simulation should show amplifier gain, distortion, and frequency response. Please include the circuit schematic showing the DC conditions, and the printouts of the gain, distortion and frequency response measurements in the project report and progress reports.
3. Build and test the circuit in the lab. You will need to personally demonstrate that you can build the circuit.
4. Submit the progress report both in writing and in person to your teacher (no less than every two weeks)
5. Submit a final report consisting of:
a. The original design calculations;
b. The schematic with the DC conditions.
c. The output displays showing voltage gain, distortion (as a function of output signal level) and frequency response for the circuit.
d. Manuscript data from your laboratory measurements, showing DC measurements, detailed drawings to scale of CRO outputs, and a careful plot of frequency response.
e. Include a discussion of the measured results compared with the calculated and simulated results. Please mention if there are any inconsistencies between the calculated, simulated and measured results, and if you believe the exercise can be improved.
f. Make sure you keep your own original documents, and submit only a copy for your report.
You must satisfy the teacher that you have personally conducted the work, and that it is largely original work, that your project represents a substantial personal effort. You must show evidence of research, regular progress, individual effort, ability to work in collaboration. Final assessment relies on your teacher’s judgement. Evidence of plagiarism in your reporting, for example uncited or extensive sections of report that are taken from other sources, will be used as grounds to reduce your grade or to fail this project. Where you use information about circuits and systems you MUST clearly identify the source of that information and how it has contributed to your understanding or to your design solution.
