Announcements (Updated 19 April 2018)

(19 April 2018) Homework solutions SOL9 are posted.

(17 April 2018) Homework solutions SOL7 and SOL8 are posted.

(12 April 2018) It looks like I never posted links to the exam 2 histogram and comparison between exam 1 and 2.

(11 April 2018 - second update) Here are some practice exams. The first was a common exam across sections, and was comprehensive, mostly on FETs but with some coverage of other material. That will not happen this time.

With solutions: EECE2412_FinalExam_Fa16_cd_mod_sol.pdf

The second only had three problems. I expect to do 4 this year, but the topics will be much the same.

With solutions: exam3sol.pdf

(11 Apr 2018) HW9 is posted. It is due next Wednesday, the 18th at the start of class.

(2 Apr 2018) HW8 is now posted. It is due on Wednesday, 11 April. There will be one more homework issued on or before that date that will be due 18 April.

(23 Mar 2018) Here are some practice exams. Please note that we are not doing the Early Effect in BJTs this year. You'll see it on the FETS in Exam 3.

F16 | Solutions
S16 | Solutions

(22 Mar 2018) HW 5 Solutions and HW6 Solutions are now posted. There is something missing in HW7; For Q3, beta = 100 and Vcc = 5 v. Remember HW7 is due next Wednesday.

(20 Mar 2018) HW7 is now posted. It is due next Wednesday, 28 March in class.

(14 Mar 2018 ) The Tuesday labs will be delayed one week from the schedule, ending on 17 April. The Friday labs will not be changed.
Ali will hold office hours tonight in the PC Lab at the usual time.
Homework due today in my section is now due tomorrow.
IMPORTANT: Our final exam is Friday, 20 April, from 1:00 to 3:00 in 129HT. If you have a final-exam conflict please bring me a final-exam-conflict form within the next week. A conflict means two exams at the same time or more than two exams in one day.

(13 Mar 2018) Here is a tentative plan for the snow day. (1) The Tuesday labs will be delayed exactly one week. That means they will end on 17 April, the day before classes end. We are waitng to verify that there are no conflicts with space or anything else. (2) There will be no change in the Friday lab schedule. (3) Ali will move his office hours to Wednesday. There is a conflict with the rooms. We are trying to resolve that. (4) Homework for my section that was due Wednesday is now due Thursday. Watch for further updates here.

(12 March 2018) Because classes are cancelled tomorrow for the possible snowstorm, the lab is also cancelled. It will be re-scheduled as soon as I can check with other parties to make sure there is no conflict. Please spread the word.

(1 March 2018) HW6 is posted. It is due the Wednesday after Spring Break. Also, Exam 1 Solutions are posted, along with a cumulative histogram of the grades.

(21 Feb 2018) HW5 is posted.

(14 Feb 2018) Below in the supplementary material, I've posted the equations for gain bandwidth product. Because the bandwith is different for the amplifier circuit with and without load, I've called the former f_{bVOL} and the latter f_b. You can also get it here.

(13 Feb 2018) Mr. Vakili will hold 2 sessions of recitation and PSpice workshop in the lab this week.
Wed 6-7 Recitation, 7-8 PSpice Workshop.
Thu 6-7 Recitation, 7-8 PSpice Workshop.

(12 Feb 2018) Solutions to HW1 and HW2 are posted above.

(10 Feb 2018) I just fixed the broken link to HW3.

(9 Feb 2018) HW3 has just been posted. It is due Wednesday the 21st.

(6 Feb 2018) Ali just informed me that he's still doing office hours well after 8pm and that there are still students struggling with HW2. We've decided to further postpone the due date until Friday. We'll work out a plan for submission between now and then.

Furthermore, he has volunteered to do extra office hours Thursday evening 6:00 to 8:00 at a location to be determined. Keep an eye on this website for further information.

(3 Feb 2018) Homework 2 submission is delayed until Wednesday. Please spread the word to your classmates. Homework 3 will be assigned this week, and due next week.

(30 Jan 2018) I've heard some problems regarding the Tegrity lectures. Please see the 26 Jan note for instructions. Tegrity classes link is on the left panel on the Blackboard site. This direct link (CLICK HERE) works for me, but I'm not sure it will for you. Be sure you are already logged into Blackboard before you try it. If you have problems let me know.

(28 Jan 2018) New material is posted by the Lab TAs, especially for Section 5. Other sections should have received this by email. See the Current Lab Information link on the third line from the top of this page or here|.

(26 Jan 2018) The lectures for this coming week are posted on the Blackboard site under "Tegrity Classes." You will probably find it useful to download my notes from 2016, which I used as presentation material in the lecture. Please note that some of the pages are out of sequence. The material to be covered starts on Page 37.

(25 Jan 2018) Homework 2 is posted above. I will collect it on Monday, 5 February. However, I recommend working on it sooner as we'll have Homework 3 posted next week. Remember that the class lectures are videos. I'm presently loading those to Blackboard.

(19 Jan 2018) The lab materials from the TA are posted above at the link to Current Lab Materials .

(17 Jan 2018) Note from the Lab TAs.

Dear Students,

Welcome to EECE 2413 Lab class. I'm Ruofan Zang (zang.r@husky.neu.edu), Andac Demir (demir.a@husky.neu.edu) and I will serve as your TA this Spring 2018 semester.

Our first lab will start in week 3, (Jan. 23rd for Tuesday sessions, Jan. 26th for Friday session), and the location is Hayden 009, Lab C. The detail of the lab will be uploaded to blackboard later this week.

Office hours: Ruofan Zang -- Monday 6:00pm - 8:00pm in Hayden 009 Lab -- -- C; Andac Demir -- he will inform you later this week.

Best regards,
Anadac and Ruofan

(16 Jan 2018) There is no lab today or Friday. Check the syllabus or lab schedule (links at the top of the page) for all the lab dates.

(12 Jan2018) HW1 is now posted. It is due at the start of class on Wednesday, the 24th.

(13 Dec 2017) Welcome to my section of EECE2412, Electronics. Please look here first for course information. I do like all the pointing and clicking that's required to use Blackboard, so I post most information (except grades) here. We will introduce you to the basic components of modern electronics, namely diodes and transistors, along with their use in a variety of circuits. There will be lectures, homework assignments, computer-based design assignments, and of course, exams. The laboratory, EECE2413, will be closely coordinated with the class material. The textbook, is Hambley, Electronics , Second Edition.
We will make use of Pspice and Matlab software in this course.
Very little will change from the last semester in which I taught the course. You may look at the Spring 2017 website to see what we did there. I'll be updating the schedule in the syllabus, and posting new homework assignments soon.

Other Resources
The textbook had a website with a variety of resources that you may find interesting. It was located at http://cwx.prenhall.com/bookbind/pubbooks/hambley/chapter0/deluxe.html, but that link doesn't seem to work anymore and I haven't found a replacement (11 Sep 2016).

Pspice information (Thanks to Prof. McGruer) PSpice (Available on NU computers or download for free). We will extensively use PSpice. The student version of PSpice is available for free. You may use any version of PSpice that you wish, but you may find it helpful to be consistent in your versions. You cannot save in version 9.1 and use in version 8.0. In fact, sometimes there is difficulty in saving in version 8.0 and then using in version 9.1, but less so. Pspice is avaliable at http://www.electronics-lab.com/downloads/schematic/013/ .
Thanks to Prof. Onabajo and one of his students for instructions for Windows-10 users.

If you want to review circuits or more problems to solve in electronics, you might find Schaum's Outlines for Electric Circuits or Electronic Devices and Circuits useful. I have not looked at these in a while but I found their earlier outlines quite useful when I was a student.

ABOUT THE BACKGROUND: My favorite winter passtime is skiing. I put this background together from a detail of a photograph taken at Park City, in 2003. There are four copies in different orientations so that the tracks (and more importantly, the brightness levels) line up as the pattern repeats.
