|14| 11/19 | 12/08 | 12/10#| 4.94,+4.96, 4.97, D4.98, 4.99, |
| | | | | 4.105, 4.106 |
|--+-------+-------+-------+------------------------------------|
|13| 11/15 | 11/17 | 11/19#| 4.90 (Note: Lab report due Friday) |
| | | | | |
| | | | | Hint for 4.90: There is enough |
| | | | | information given to compute the |
| | | | | overdrive voltage. From this you |
| | | | | can determine the region of |
| | | | | operation even though you do not |
| | | | | know the threshold voltage. |
|--+-------+-------+-------+------------------------------------|
|12| 11/03 | 11/12 | 11/15#| +4.79, D4.80, +4.85, 4.86, +4.91 |
| | | | | |

|11| 10/27 | 11/03 | 11/05#| *4.67, 4.69, 4.74, 4.77, 4.78 |
| | | | | |
| | | | | Note: See errata for problem 4.74.|
| | | | | |
| | | | | Note: For problem 4.78 a generic |
| | | | | sketch with no numbers on the axis |
| | | | | but with critical points labeled |
| | | | | is desired. The main part of the |
| | | | | problem is the proof ("Show. . .") |
| | | | | and the sketch is intended to |
| | | | | illustrate the proof. |
| | | | | |
|--+-------+-------+-------+------------------------------------|
|10| 10/22 | 10/27 | 10/29#| +4.46, *4.47, 4.49 (suggest using |
| | | | | a computer, eg Mathcad or Matlab |
| | | | | or equivalent to do this problem) |
| | | | | |
| | | | | 4.51, D4.55 except use 2.2 Mohms |
| | | | | for the larger of RG1 and RG2. (A |
| | | | | factor of 10X smaller than the |
| | | | | text recommends--this is more |
| | | | | practical.) |
| | | | | |
| | | | | +D4.65 |
| | | | | |
| | | | | Hint on 4.46 part (b): Do not |
| | | | | carelessly round V4 and then use |
| | | | | that inaccurate number to find I3. |
| | | | | |
| | | | | Note: be sure to check the errata |
| | | | | on problem +4.46. Also check the |
| | | | | errata on the answers to this |
| | | | | problem. |
| | | | | |
| | | | | Note: see errata on problem 4.49. |
| | | | | |

| | | | | 4.18, +4.20, *4.33, +D4.34 |
| | | | | |
| | | | | Note errata (below) on 4.18 and |
| | | | | the answer to +D4.34 |
|--+-------+-------+-------+------------------------------------|
| 8| 10/06 | 10/13 | 10/15#| *D3.69, |

| | | | | Note: For part d assume the input |
| | | | | signal, vI, is periodic and has |
| | | | | been running for a long time. |
| | | | | Hint: You can simulate these |
| | | | | circuits in PSpice using an ideal |
| | | | | diode model (Simulation is |
| | | | | optional--I want you to be able |
| | | | | to explain how the clamp works, not|
| | | | | just how to make PSpice do a plot.)|

Note 1) If a "#" follows the "returned" date, then the solution
key is posted on the cork board across the hall from room S233.
Note 2) Problems sets shown above with no "assigned" date are
tentative. More problems might be added, expected due dates
might change, but problems shown will eventually be assigned.
Note 3) A "+" mark in front of the problem number means an answer
is in the text, in Appendix H.
Note 4) Asterisks (*) indicate more difficult or more time-
consuming problems. The more asterisks, the more difficult.
Note 5) The letter "D" in front of a problem number indicates a
design oriented problem. The student may need to use some
judgment in understanding what the problem statement is
requesting. (Ask Prof. De Boer if you are in doubt.)

TESTS (Last update: 12/08/04)
-----
Test #1, Wednesday, 9/29, The test covered Chapters 1 and 2 and
Sections 3.1 and 3.2 in Chapter 3, except section 1.7 (Digital
Logic Inverters) was be omitted. Review of labs 1 through 3
was advised since these labs reinforce material presented in
the text. One crib sheet (8.5 x 11 inches), both sides, was
allowed. Closed book. A calculator was required. Grading is
in progress. Average raw score was 74 out of 100. Minimum
raw score for each grade was: A = 91, A- = 85, B+ = 77,
B = 71, B- = 67, C+ = 63, C = 58, C- = 52, D+ = 46, D = 41,
D- = 36, F = 0.
Test #2, Wednesday 11/10.
Type: closed book, two crib sheets allowed. A calculator is
needed.
Coverage: Chapter 3 Section 3.3 through Chapter 4 Section
4.6. The subjects in the labs and in the lab project may also
be covered, however there will be no questions that require
knowledge of the SPICE language or the PSPICE or ORCAD
programs. There also will be no questions on diode device
physics. This means specifically that section 3.7 will be
omitted from the test. Material on test #1 is prerequisite
for this test.
Results: Handed back on Friday, 11/12. Avg raw score was 72
out of 100. Minimum raw score for each grade was: A = 87,
A- = 81, B+ = 74, B = 70, B- = 66, C+ = 61, C = 56, C- = 50,
D+ = 45, D = 40, D- = 35, F = 0.
Final Exam, Saturday 12/11 from 3:30 to 5:30 pm.
Type: closed book, three crib sheets allowed. A calculator is
needed.
Coverage: The entire course with emphasis on each topic roughly
proportional to the time spent on the topic. Material covered
on the final exam is everything covered in the lists above for
Tests #1 and #2 plus all the lab handouts and homework
assignments, plus Chapter 4 through Section 10. There will be
no questions on the final exam that require knowledge of the
SPICE language or the PSPICE or ORCAD programs. There also
will be no questions on diode device physics (section 3.7).
Grading Status: Grading has not started yet.

| 5| 9/29 | 11/19 | | Design of an unregulated DC power |
| | | | | supply. Three design objectives: |
| | | | | |
| | | | | 1.) Get the maximum DC power from |
| | | | | a given transformer. |
| | | | | |
| | | | | 2.) Ripple less than 0.25 V p-p |
| | | | | |
| | | | | 3.) A SPICE model of the |
| | | | | transformer, the model to be used |
| | | | | in simulations which correlate to |
| | | | | the performance of your designed |
| | | | | DC power supply. |
| | | | | |
| | | | | A formal lab report will be |
| | | | | required. Due date not yet |
| | | | | established, probably late October.|
| | | | | |
| | | | | Three weeks have been planned for |
| | | | | this lab, 9/29, 10/6, 10/13. |
| | | | | |
| | | | | This lab was extended two more |
| | | | | weeks, 10/20, 10/27. |
| | | | | |
| | | | | Grading status: Grading is in |
| | | | | progress. |

| 7| 11/10 | --- | --- | MOSFET Single-Stage CS Amplifier |
| | | | | |
| | | | | Use a TN0606 MOSFET to create a |
| | | | | CS amplifier to drive a 1 Kohm |
| | | | | load. The 1 Kohm load and the |
| | | | | input signal must be capacitively |
| | | | | coupled. Design goals listed from |
| | | | | highest priority to lowest are: |
| | | | | |
| | | | | 1.) Maximum output amplitude |
| | | | | 2.) Freq. response 20 Hz - 20 kHz |
| | | | | 3.) Minimum distortion. |
| | | | | |
| | | | | You should build a laboratory |
| | | | | prototype and do suitable tests |
| | | | | on it. SPICE (PSpice) can be |
| | | | | useful as well, especially to |
| | | | | verify initial design calculations.|
| | | | | |
| | | | | 11/17, 12/01, 12/08 |
| | | | | Four weeks were allowed for this |
| | | | | project. (11/10 11/17 12/01 12/08) |
