Help Sessions for Nov. 17–21 - SECOND UPDATE (11/21/2025)

I plan to be available at least at the following times this week:

• Monday 5:00–6:00 pm (BRKI 368)
• Tuesday 5:00–5:45 pm (BRKI 368)
• Wednesday 5:00–5:45 pm (BRKI 368)
• Wednesday 10:00–11:00 pm (Zoom)
• Thursday 10:00–11:00 pm (Zoom)
• Friday 10:00–11:00 am (back in BRKI 368)

I am usually also available at the end of my MWF lectures at 9:50 am in Dana 307 and at 4:50 pm in BRKI 165.

Guidelines and additional information:

• Please contact me if you have a conflict with these times and would like to arrange a meeting at a different time.
• The Zoom link is available at the course Moodle site.
• If I am helping another student when you drop by, you may usually join in the conversation.
• If I have been helping you for a relatively long time, I might pause our conversation to help other students who are waiting for assistance.
• For in-person sessions, if I have finished helping you, please move out to the hall or somewhere else so that the chairs in my office are clear for newly arriving students.
• As a courtesy during Zoom sessions, please use your camera.

Selected Answers to HW #7 (11/20/2025)

The answers to selected graded problems in HW #7 are now available on the Homework Assignments page.

Exam #3 Solutions (11/20/2025)

The solutions to Exam #3 are now available at the course Moodle site.

Exam #3 Results (11/20/2025)

The average score for Exam #3 was 83.2. The average score breakdowns for the individual problems (converted to percentages) were:

• Prob. 1 - 91%
• Prob. 2 - 92%
• Prob. 3 - 71%
• Prob. 4 - 81%
• Prob. 5 - 81%

HW #7 Revised (11/20/2025)

The original version of Graded Prob. 2 of HW #7 incorrectly referred to the amplifier circuit considered in the previous problem. It should have referred to the amplifier considered in the next problem. A revised version of the HW #7 assignment has been posted.

Matlab Simulation of CS Amp (11/18/2025)

The Matlab files used to generate the animated simulation of the operation of the MOSFET common-source (CS) amplifier that was presented in class recently are now available at the course Moodle site in the Additional Resources section. There should be three files in the folder accessed by the link; you need all three to run the simulation on your own computer or on a university computer. I recommend that you place the files in their own folder.

Matlab must be installed on the computer on which you plan to run the simulation. If you are off-campus, you will need to activate the Bucknell VPN to use Matlab under the university's license.

HW #7 (11/16/2025)

The assignment for HW #7 is now available. It is due via Moodle at 11:59 pm on Friday, November 21.

Reading Assignments for Nov. 17–21 (11/16/2025)

• M: Sections 7.3.5, 5.1.7, 5.1.8, 5.2.5, and 5.3 (focus on PMOS examples)
• W: Introduction to Part III, Subsections 16.1.1 and 16.1.2, and Sections 16.2 and 16.3
• F: [canceled]

The Monday readings from Chapter 5 all focus on p-channel MOSFETs (PMOS devices). In Section  5.3, focus on the examples that involve PMOS devices.

Focus on Subsection 16.2.2 when you read Section 16.2. The introduction to Part III of the textbook includes a brief history of the development of digital logic circuits that helps provide context for the material in Chapter 16.

Class Canceled on Friday, Nov. 21 (11/14/2025)

Because Exam #3 was scheduled outside the regular lecture time, the class meeting on Friday, Nov. 21 will be canceled.

Exam Formula Sheet (11/11/2025)

A formula sheet containing most of the important hard-to-remember equations that we have used during the second half of the semester and other information will be provided to you during Exam #3 and the Final Exam. A copy of the formula sheet is now available at the course Moodle site in the "Additional Resources" section for your review beforehand.

During Exam #3, you will be allowed to use up to three handwritten help sheets that you have prepared yourself in addition to the formula sheet.

HW #6 Solutions (11/11/2025)

The solutions to the graded and ungraded problems in HW #6 are now available at the course Moodle site.

Review Session for Exam #3 - UPDATE (11/10/2025)

To help you prepare for Exam #3, an optional review session will be offered at 8:30 pm on Monday, November 10 in Breakron 166. The exam room is not available at that time.

The format of the review session will be the same as the previous ones. I strongly suggest that you come prepared with questions.

If you cannot attend the review session but would like to meet with me at another time before the exam, please contact me.

Help Sessions for Nov. 10–14 (11/9/2025)

• Wednesday 5:00–6:00 pm (BRKI 368)
• Wednesday 9:00–10:00 pm (Zoom)
