Homework
- You will receive zero credit for writing down the correct answer. To receive credit, you must document clearly what principles you used to solve each problem and the steps you followed. One of the objectives of this course is to develop your skills in writing technical reports. A key to success in writing technical reports is documenting and explaining your work to other professionals. You must clearly document and explain your work to the grader to receive credit for each homework assignment.
- Homework is due at the beginning of the class period on the date specified in the Schedule.
- Late homework will not be accepted after the beginning of the class meeting on the date specified in the Schedule. You will receive no more than 75% credit for late homework.
- Your homework grade will be determined by your best n-2 (out of n) grades on the homework assignments.
- You are encouraged to develop and share ideas for solutions of homework assignments with others in the class but the work you submit cannot closely duplicate that submitted by another student. The work you submit must demonstrate clearly to the grader your personal, individual effort. For example, neither words of explanation, graphics (including screen shots), nor the format of MATLAB® commands should duplicate those in the work of another student. Even though you work cooperatively with others, you must demonstrate to the grader that you did not merely replicate the work of someone else. Excessively similar submissions will earn a grade of zero. In addition, a report of academic misconduct will be filed according to the Policies and Procedures for Handling Academic Misconduct.
Attendance
Students are expected to be present for all tests and for the final exam. In extreme cases, I may arrange a make-up test. I will not be taking regular attendance, but I strongly suggest coming to class as the tests are based off of material discussed in class. It is the student's responsibility to contact me in advance to explain the situation and arrange an alternate plan.
Academic Dishonesty
You may discuss work, and verbally answer questions about work from other students. You may not show your work to another student or provide an old copy as an example. Looking at or copying any material (schematics, HDL files, simulation files, scope plots, etc.) from another student is considered academic dishonesty. The person providing this material would also be guild of academic dishonesty. If I find a student guilty of academic dishonesty, expect an F in the course and an academic dishonesty claim to go into your permanent academic record. For graduate students, an F in any course results in immediate expulsion.
Labs
- According to the laboratory schedule, each student will build and test a working prototype of a high performance audio power amplifier on a printed circuit board (PCB).
- Before or during each scheduled laboratory session, each student will complete the specified tasks, will record the results into the laboratory notebook, and submit the work to the teaching assistant for evaluation.
- For Laboratory 8 (after completion PCB design), each student will write and submit an interim laboratory report before the end of the scheduled time for that laboratory session. The main purpose of the report is to describe to the teacher and the teaching assistants the progress and problems, as well as well as their resolution, in accomplishing the task of building the working prototype. The report will also describe the basic operation and function of the various subcircuits of the given amplifier design.
- For Laboratory 12, each student will write and submit a final laboratory before the end of the scheduled time for that laboratory session. The final report will expand the interim report to include work on laboratories 9, 10, and 11, and will incorporate improvements in content and style that arise from evaluation of the interim report. The report also will compare the Lin architecture of the audio amplifier with that of a 741 operational amplifier Sedra/Smith pp. 893 - 898) and the LM380 IC power amplifier (Sedra/Smith pp. 1261 - 1264).
- A student who fails to complete and submit a notebook for review, or a report before the end of the laboratory session at which it is due will receive no more than 90% credit for that work when it is submitted later.
- The laboratory grade will be calculated as follows:
- 40%: Weekly laboratory notebook evaluations.
- 15%: Interim laboratory report.
- 20%: Final laboratory report.
- 5%: Milestone 1, successful Cadence PSpice simulation of the frequency response of the given design.
- 5%: Milestone 2, receive PCB from Advanced Circuits.
- 5%: Milestone 3, fully populate the PCB with components from the parts list.
- 10%: Milestone 4, demonstrate operation of the Slone 12W amplifier with third harmonic distortion of 1% or less at 1kHz.
- 10%: Bonus Milestone: demonstrate operation of the Slone 12W amplifier with THD distortion of 0.01% or less at 1kHz.

Software Instruction
If for some reason you do not feel secure with the pSPICE circuit simulation utility you might take a few moments and walk through these tutorials. They are slow and patient, and will help to get you started and into the more important aspects of pSPICE that are needed for expert circuit simulations:
- Tutorial #1: Getting Started - pSPICE Schematics editor.
- Tutorial #2: Execute pSPICE and invoke the PROBE (output display) window.
- Tutorial #3: Set up parametric sweep option. Example: Maximum power transfer theorem via pSPICE.
- Tutorial #4: Load MOSIS parameters into generic MOS part. Example: I-V characterstics for short-channel transistor.
If you do not have a copy of the student version of pSPICE, go get one at the ORCAD/Cadence (updated) site. It should be a straightforward download and install. If for some reason this copy is not friendly (sometimes also called 'vendor improved') then you can obtain an old reliable copy at pspice(olde).
PSPICE examples
- Analysis of differential pairs - Common-mode rejection ratio (CMRR) assessment using pSPICE for Emitter-coupled pair (ECP) and for Source-coupled pair (SCP).
- Active-mode Differential pairs - pSPICE assessment of micropower (low current-level) ECP.
- Frequency-domain analysis for electronic circuits - roll-off corners using pSPICE for CE configuration and 2n3904 BJT part and for CS configuration using 2-micron technology MOSIS parameters.
- Class exercise using 0.5-micron technology MOSIS parameters, for FET cascode circuit.
- Class exercise illustrating R-2R ladder with opamp backend.
- Homework exercise on CMRR of differential amplifier with non-ideal opamps.
- Homework exercise on slew rate, non-ideal opamps.
- Homework exercise on Sallen-Key biquad with non-ideal opamp
- Homework exercise on Tow-Thomas biquad and extraction of rolloff in dB/decade.
