EE327: Electric Circuits Laboratory

Winter 2003

Instructor: Ling Zhang

Lab Hours: Tuesday 1:30PM-----5:18 PM / Thursday 1:30PM-----5:18PM

Email address: zhangli@ece.osu.edu

Textbook:

Lab Notes: EE327 Course Packet, available at COP-Ez (open 24 hrs/day)

Reference Book: Microelectronic Circuits, 4^th Edtition by Sedra/Smith

Grade Weighting:

Quizzes 20%

Lab Reports 40%

Lab Clean-up 10%

Final 30%

Labs:

· Students are required to attend all labs.

· Students should work in groups of two or three.

· Each group should maintain one lab notebook to record the weekly data and schematics (complete with component values). This notebook should be kept in ink.

· Each group should prepare a floppy disk to store the display on the oscilloscope. Use “print to disk” instead of “print to a printer” when trying to storing data on the oscilloscope.

Lab Reports:

· Each lab group will submit only one lab report at the beginning of the next lab session.

· Lab report will be penalized 10% per day.

· Report grading methodology:

§ Lab work (30%)----evidence of having successfully completed the lab tasks.

§ Figures/Tables/Equations (20%)----the solid content of the report

§ Discussion (50%)

o Purpose ---- why we did it

o Procedures ---- what we did

o Theoretical results ---- what we should have seen

o Measurement results ---- what we did see

o Conclusions ---- why we see what we did

Quizzes:

· There is a quiz each week, at the beginning of class, on the material in that day’s lab (do not be late; you may not have time to complete the quiz)

· The quizzes are closed book, closed notes.

Final:

· There will be no final project.

· Final will be open book, open notes .

· It will be on the class schedule.

Tips:

· It is very important to read the corresponding lab instruction and its theory before each lab. It will give you a clear picture of what you are trying to achieve in the lab. And also, it will make you well prepared for the quizzes.

· Proof read the lab reports. Have someone other than the author read the reports as well.

· Record details immediately, especially component parameters, schematics, and data measurements in a lab notebook.

· Write the data neatly in the lab notebook.

· Be sure to note any discrepancies or unexpected phenomena immediately, this will help explain your measurement results in the report.

· Be ware that the breadboards and components in this lab are questionable. If a circuit is not working, (1) question the wiring, (2) question the component, (3) question the breadboard.

· Always watch the current meter on the power supply when turning on the power.

· Leave the benches as they are now. All power is off (including the meter ) and power knobs set to zero, AND the benches are clean.

· Orient all chips in the same direction.

· Conserve breadboard space. There are 7 labs to be on your board.

· PNP = 2N3906

· MOS switch = CD4066

· V_DD = V_CC

· V_EE = V_SS

· Do not wire across chips to power; go to the nearest power rail.

· Use small wires, especially for power.

· Wire the power first.

· Always record & use measured resistance values for theoretical equations.

· Verify the functionality of each component, if possible.

Because of the restructuring of the circuits and electronics curriculum, the order of the labs contained within this lab has been changed. This change represents a system-level point of view of electronics, which is more consistent with the revised electronics curriculum. The above schedule reflects the order in which the seven labs of the EE327 manual will be completed, starting with lab four, Oscillators. Be sure to read the appropriate lab manual section each week.

Lab Report Writing Strategies

When writing the lab reports, please stick to the following rules.

· Use a title page, including title, bench #, name of group member.

· Lab report should be typed, except for the print-outs from the oscilloscope.

· Be sure to use any relevant equations when comparing theoretical and measured results and to use the measured component values when calculating theoretical results.

· All pages should be numbered.

· When applicable, use percent error to describe how a circuit functions.

· Keep the report simple. Be complete but concise.

Figures/Tables/Equations:

· Equations/figures/tables should be numbered in numerical order. (Figure1 always precedes Figure2, and Figure2 always precedes Figure3, but of course Table2 can come before or after Figures 1,2 or 3).

· Print-outs should be inserted within the report (not at the end). Either paste them in or insert an entire page for it.

· Each figure should be labeled. For print-outs, handwritten labels are acceptable.

· Tables and figures should always have descriptive captions, which are properly placed.

· Do NOT include a figure unless the text says something about it.

· Once a figure has been included, tell the reader what is important to notice about it.

· Figures should not span multiple pages.

· Insert actual oscilloscope print-outs from the lab; do NOT insert scanned or photocopied oscilloscope print-outs.
