|12| 12/06 | 12/13 | | Read 5.1 |
| | | | | |
| | | | | Do +5.1, +5.3, +5.4, 5.5, +5.6, |
| | | | | 5.10, +5.12, +5.13 |
| | | | | |
| | | | | Note errata for +5.1 (Please |
| | | | | ignore the alternative in the |
| | | | | errata.) |

|11| 11/29 | 12/06 | 12/11#| Review 4.9, Read 4.10, 4.11 |
| | | | | |
| | | | | Do 4.97, D4.98, +D4.99, 4.105, |
| | | | | +4.106, 4.115, 4.116 |
|--+-------+-------+-------+------------------------------------|
|10| 11/13 | 11/15 | 11/29#| Read 4.9, Do 4.94, +4.96 |
|--+-------+-------+-------+------------------------------------|
| 9| 11/03 | 11/08 | 11/29#| Read 4.8, 4.9 |
| | | | | |
| | | | | Do 4.90, +4.91 |
| | | | | |
| | | | | 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. |
| | | | | |
| | | | | Note: Since we did not get to the |
| | | | | Miller Theorem in our class |
| | | | | discussion on Monday, 11/06, the |
| | | | | problems that were assigned in Sec.|
| | | | | 4.9, namely 4.94, +4.96, 4.97, |
| | | | | were moved to the next assignment. |
| | | | | |
| | | | | Study for test on Friday, 11/10 |
|--+-------+-------+-------+------------------------------------|
| 8| 10/27 | 11/01 | 11/08#| Read 4.7 |
| | | | | |
| | | | | Do +4.79, D4.80, +4.85, 4.86 |
| | | | | |
| | | | | Note on 4.86: The coaxial cable is|
| | | | | just a (fancy) wire. No current |
| | | | | flows from the center conductor to |
| | | | | the shield. The "50 ohm coaxial |
| | | | | cable" label on the figure will be |
| | | | | explained in class. |
| | | | | |
| | | | | Note errata for 4.86 |
|--+-------+-------+-------+------------------------------------|
| 7| 10/18 | 10/25 | 10/27#| Read 4.5, 4.6 |
| | | | | |
| | | | | Do *4.47, 4.49 see errata on 4.49, |
| | | | | |
| | | | | D4.55 except use 2.2 megohms for |
| | | | | the larger of RG1 and RG2. (A |
| | | | | factor of 10X smaller than the text|
| | | | | recommends--this is more practical)|
| | | | | |
| | | | | +D4.65 and see errata on the |
| | | | | answer to +D4.65, |
| | | | | |
| | | | | *4.67, 4.69, 4.74, 4.77, 4.78 |
| | | | | |
| | | | | Note errata for 4.74 |
| | | | | |
| | | | | For problem 4.78 a generic sketch |
| | | | | with no numbers on the axes 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. An initial |
| | | | | sketch might be easier to make if |
| | | | | you assume numeric values for the |
| | | | | transistor's parameters, but keep |
| | | | | the proof and final sketch generic.|
|--+-------+-------+-------+------------------------------------|
| 6| 10/11 | 10/18 | 10/23 | Read 4.3, 4.4 |
| | | | | |
| | | | | Do D3.99, **3.105 Also assume C is |
| | | | | fully charged and operating in the |
| | | | | steady state. Hint: these diode |
| | | | | circuts can be quickly built and |
| | | | | tested in the lab or simulated in |
| | | | | PSpice. (e.g. use 1N4004 diodes in|
| | | | | the lab or an ideal model in PSpice|
| | | | | along with 25 kohm resistors and |
| | | | | 1 uF non-polarized capacitors.) |
| | | | | +4.12, 4.18, +4.20, *4.33, +D4.34, |
| | | | | +4.46, +4.51 |
| | | | | |
| | | | | Note errata on 4.18 and the |
| | | | | answers to +D4.34 |
| | | | | |
| | | | | Hint on 4.46 part (b): Do not |
| | | | | carelessly round V4 and then use |
| | | | | that inaccurate value to find I3. |
| | | | | Also note errata on 4.46 |
| | | | | |
| | | | | +4.11 was accidentally double |
| | | | | posted in both PS#5 and PS#6. On |
| | | | | Monday afternoon, 10/16, it was |
| | | | | deleted from PS#6. |

+---------------------------------------------------------------+
Note 1) The text includes "Exercises" embedded throughout the
reading assignments and "Problems" at the end of each chapter.
All the assignments refer to "Problems" unless they are prefixed
with "Ex". Example: Ex1.5 is found on page 10 but 1.5 is found
on page 51.
Note 2) A "+" mark in front of the problem number means an answer
is in the text, in Appendix H.
Note 3) 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.)
Note 4) Asterisks (*) indicate more difficult or more time-
consuming problems. The more asterisks, the more difficult.
Note 5) If a "#" follows the "returned" date, then the solution
key is posted on the cork board across the hall from room S233.
Solution keys will usually be posted shortly after homework is
returned.
Note 6) 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 7) If you are having difficulty reading the latest version
of this page it may have to do with your browser's cached memory.
Read this note on cached pages to solve the problem.
