• 8727: F
• 8801: A
• 8958: A+
• 9150: B
• 9339: B+

The pdf grades file now also includes grades for the lab section.

Final exam scores and final course grades can be found here. Data is sorted by the last 4 digits of your student ID number.

Final grades for the lab portion of the class will be posted later (perhaps tonight).

All grade disputes (lecture and lab) MUST be resolved by 11 pm on Monday, June 18th. There are no extensions possible beyond this time, as grades need to be submitted the next morning.

If you want to dispute your grade, I would recommend that you first use the spreadsheet on the class web page to see where you actually stand in terms of points and how close your are to the grade you want.

If your dispute is specifically related to the final exam, you will want to review the answer key and see how close your actual answers on the exam were to the answer key.

Final exam stats: Average = 27.29, Stdev = 10.23
• If you got above 40, it's an A.
• If you got between 33 and 39.5, it's a B.
• If you got between 27 and 32.5, it's a C.
• If you got between 17 and 26.5, it's a D.
• If you got below 16, it's an F.

Final exam scores and final course grades will be posted here before 6 pm today.

Solutions to the last set of homework problems (Chapters 6 and 9) have been posted below. You now have everything you need for Wednesday's final exam.

Two pages of notes are allowed on the final. (8.5" x 11" paper, both sides)

Solutions to the Chapter 8 homework have been posted below. Solutions to the last homework set will be posted on Sunday. Please do the homework problems first before consulting the solutions.

All unclaimed homeworks have been left in the EE 171 lab. You'll find them next to the laser printer. Please pick them up by Friday. (BELS may lock out access to the lab starting next week)

Additional office hours are available next week if you happen to be near Santa Clara University. I'll be there on Tuesday (6/12) from 3:15 pm to 4:45 pm. My office is at Cesar Chavez 124B. It's a trailer building located just off of Franklin Street. There is plenty of parking along that street or on nearby side streets. A map of the university can be found here.

We may have time to do review in class on Thursday. Please look over what we've covered this quarter and come with questions to class.

From the last lecture (lec19.pdf), please print out and bring slides 24 and 25 with you to class next week. You will need them in order to complete the student evaluations.

For those of you doing the extra credit work over the next 2 weeks, please show up to my office on time. Your time ends promptly at 10:30 am or 11 am, regardless of when you show up. Please also bring your simulation decks on a USB drive or on a 3.5" floppy. (read the assignment to figure out which files you need) We will run the simulations from a computer in my office.

Office hours will be held during the last two weeks of the quarter. They will be from 11 am to 12 noon in BE 129. (those of you doing the extra credit assignment need to meet me there at your scheduled times)

All time slots for extra credit are taken up (last reservation accepted at 8:30 pm earlier this evening). If you want to do the extra credit, you can try to team up with someone who already has a time slot reserved, under the following guidelines:
• Groups can be no larger than 2 students.
• The person who originally received the reservation reserves the right to do the assignment himself/herself. (no peer pressure, please)
• You need to email me if you decide to work with another person (and tell me who that person is).
• You need to work together on the assignment.

Please also keep in mind that the extra credit is only worth 5% of your overall grade. Doing the extra credit is NO guarantee that you will pass the course. You still need to do well on the final. Students who fail both exams may not receive a passing grade for this course, regardless of their performance on the extra credit.

In addition to bringing the simulation files to office hours, you'll also need to bring printouts of the circuit and all simulation results (just in case there are issues loading/running the program).

For those of you who did poorly on the midterm exam (D or F only), I've added an extra credit assignment which will need to be presented to me during office hours. You will need to sign up for a time by emailing me. Only 8 time slots are available. Before starting the assignment, sign up for a time slot.

All re-grade requests for the midterm exam go through the instructor. You can talk to me either before or after class about your exam.

I've added a link below to a pdf file (via Wikipedia) on the Widlar current source. They do a pretty good treatment of the output resistance calculation (using a small signal model). It is worth reviewing, in my opinion. A similar pdf file can also be found on the Wilson current source (which will be covered on Tuesday).

Additional ORCAD circuit files have been added below. We will be relying on this tool more in the second half of the class.

I've made corrections to a few slides from today's lecture and also one slide from the lecture on BJT small signal analysis. Changes are noted below. Note that gm and rd can be found algebraically and do not require the graphical IV characteristics.

The class schedule has been updated to reflect what we'll be covering in the 2nd half of the class. Topics after 5/31 may be adjusted.

Midterm solutions can be found below. Please note the following errors:
• #12: Ib should be negative, not positive. This will result in a positive value for the gain.
• Extra credit: Zin should be 55.9 ohms (posted answer is off by 10x)

Please bring separate paper or a blue book to the midterm exam tomorrow. There is not enough room on the exam for you to write your answers or show your work. (i.e. all work and results to be shown on separate paper)

Unclaimed homeworks for Chapter 3 can be picked up in the EE 171 lab. (look for the stack of papers above the function generator, next to the printer)

For the common-emitter simulations, be careful about what you define as input. In class, the gain was only 50 because the input was defined as "Vs". If you define the input as the voltage drop across the 5k resistor, you will get results that match those in the textbook.

Homework problems for Chapters 5 and 7 have been posted below.

Homework solutions for Chapter 4 have been posted below. You now have all materials for this week's midterm exam.

Solutions to the Chapter 3 homework are posted below.

Unclaimed Chapter 2 HW's can be picked up in the EE 171 lab. Next time, whoever has the stack of homeworks last should pass it on up to me at the end of class, instead of leaving it in the classroom.

With the midterm exam coming up next Thursday, I will hold office hours in the EE 171 lab on Tuesday (5/1) of next week from 10 am to 1 pm.

You will be allowed to use one page of notes on the midterm exam. (8.5" x 11" sheet of paper, both sides)

Under "Course Resources", I've added another zip file which contains schematics and PSPICE simulations for the exercises and figures in the textbook. To open any of these files, use the "Capture CIS" application to open the "OCR Project" file and then convert the project (put the project into a directory that you can write to). You then should be able to run the PSPICE simulation and look at the results. them

Tutoring sessions are no longer being held at the whiteboards. Please refer to the discussion forum link for the new location. As a reminder, all future changes and annoucements about the tutoring sessions will be made on the forums.

Homework policy: homeworks need to be submitted in class, preferrably at the beginning. Once I pass on the homeworks to the reader, no other homeworks can be submitted for grading. Late homeworks will no longer be accepted. This is to ensure that solutions are posted on the class web page in a timely manner.

Solutions to the 2nd homework assignment are posted below.

Chapter 4 homework problems have been posted below. Solutions will be posted on Tuesday, May 1st. Please try to finish the problems before then. (looking at the solutions before you've done the problems serves no purpose)

Lecture materials through the midterm exam are now posted.

Since homework now counts as part of your total grade, I have removed tutoring session attendance as counting towards your grade. The midterm and final exam will be weighed more heavily to account for this change. For more details, refer to the syllabus, which has been revised.

The link to the lecture on diodes has been fixed. You should now be able to download the lecture 5 material.

Under "Course Resources" below, I've placed a sample design file that corresponds to Figure 3.33 in the textbook. This is for use with the OrCAD software that came with the PSPICE textbook. Unzip the file contents into a directory and then open up the project using the "Capture CIS" application.

There is also a text file which contains some notes and tips on using the program. You may find this program useful in checking the answers to some of your homework problems.

If you have issues using the design I downloaded, you'll need to bring your computer (assuming it's a laptop) to class. Otherwise, you'll have to install some sort of program (like VNC) so that the problem can be debugged via the internet. (alternatively, just go through the content in the Tront book and trying using the concepts on one of the circuits you see in the textbook)

Since we won't get to diode logic at this point in the course, 3.42 has been removed from this week's homework set.

A job fair will be held by the UCSC Career Center next week. More details can be found here.

Lecture materials for the next 1.5 weeks have been posted below.

Solutions to the Chapter 1 homework can be found below.

Tutoring sessions for EE 171 start tomorrow. Refer to the discussion forum link below for more details. All future issues related to tutoring sessions will be posted on the discussion forum.

Revised office hours for the TA: Fridays from 3 pm to 5 pm. Office hours for the TA start up next week.

Office hours for the TA: Mondays and Thursdays from 3 pm to 5 pm at E2-246.

EE 171 labs will be held at the following times:
• Tuesdays from 2 pm to 4 pm
• Wednesdays from 11 am to 1 pm

Please go to the lab that fits your schedule the best. Labs are held in BE 150. You may be asked to switch to the other lab if too many people go to one lab and not enough to the other. For more details or questions about the lab, talk to the TA.

Lecture notes for this week have been added to the class web page below.

The syllabus has been revised to reflect the addition of homework as part of your grade. All changes are indicated in red.

Revised homework problems for Chapters 2 and 3 have been posted. A reader for this class has been found, so homework will be collected and graded, starting with Chapter 2.

A revised syllabus, indicating how much homework counts for your final grade will be posted shortly.

I'm going to make some corrections to the homework problems for Chapters 2 and 3. They will be reposted to the class web page in a few days. There will be no changes to the Chapter 1 homework.

Materials for Spring Quarter have been posted below. Additional items will be posted as the quarter progresses.

Materials for Spring Quarter will be available soon.
