| Note 1) |
Our Textbook, Microelectronic Circuits, by Sedra, Smith,
et. al., includes four kinds of problem solving. Generally
only the first kind described here, "Problems"
are assigned. a.) Problems are found at the end of each chapter. All the assignments refer to "Problems" at the end of the chapter unless they are prefixed with "Ex". Example: The first problem assigned in this class, 1.5, is found on page 46. Problem 1.5 starts with the phrase, "In the analysis. . ." If you are looking at something else, it is not the assigned problem. (Ex1.5 is found on page 12 and Ex1.5 is not the assigned problem). b.) Exercises are embedded throughout the body of the chapter contents. These have answers, but not complete solutions. Students should challenge themselves to solve some of these exercises. A few of these may be assigned as homework. If so, on this page their number will be prefixed with "Ex". The first exercise, Ex1.1, starts near the bottom of page 8. Exercise 1.1 starts with the phrase, "For the signal-source. . ." c.) Examples are embedded throughout the body of the chapter contents. These have complete written solutions in the textbook. Some of the homework may parallel these examples. The first example, Example 1.1, is on page 7. Example 1.1 starts with the phrase, "The output resistance. . ." d.) Video Examples are embedded throughout the body of the chapter contents. These have complete solutions presented via video accessed by Web. Some of the homework may parallel these video examples. The first video example is on page 5. Video Example VE1.1 starts with the phrase, "For the circuit shown. . ." Some of the video examples are free and some are paid "premium" content. Students should watch some of these, choosing especially the video examples on topics that are found challenging. However, the "premium content" need not be purchased. You can always ask Professor De Boer about topics you find challenging. |
| Note 2) |
Discussion in class is an important part of working the
assignments. After the first few assignments, most of the
homework for this class will be too complex to do in one sitting.
Students must be prepared to discuss the assignments in class
starting with the class following the "Assigned" date.
|
| Note 3) |
A "+" mark in front of the problem number on this page means an
answer is provided in an online appendix to the textbook. The
"+" marks do not appear in the textbook. Solutions are in
Appendix L. Also available on Canvas, Appendix L9.
|
| Note 4) |
The letter "D" in front of a problem number indicates a
design-oriented problem. The student may need to use some
judgement in understanding what the problem statement is
requesting. (Ask Prof. De Boer if you are in doubt.)
|
| Note 5) |
Asterisks (*) indicate more difficult or more time-consuming
problems (in the authors' judgement). The more asterisks, the
more difficult.
|
| Note 6) |
If the "Returned" date is a link, then the solution key is posted
on Canvas@Dordt. Click on the returned date to go directly to
the solution key.
|
| Note 7) |
Problem 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 8) |
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.
|
| Note 9) |
If a link brings you to a login page use your Dordt University
network username and password. If this brings you to the opening
page of Canvas@dordt instead of the resource you wanted, click
your browser's back arrow as many times as needed to return to
the link on this page, then click the link again. Now that you
are signed in the link will work properly.
|
| Note 10) |
We will turn homework in electronically this semester. Click
a due date (the due dates are links) to get instructions from
canvas for turning your work in. The recommended format is a
single pdf file from a scanner. Another alternative is a a
word-processor file (docx for example) with photos from a
smartphone of your homework pasted into the document. If you
use this alternative, please consider using a "mobile scanner
app" in your smartphone to get a nice contrasty picture of
each homework page.
