  • Final Announcements
    • The Final will be held on Thursday 12/13 from 8-11 am in 155 Dwinelle.
    • Please try to come to the classroom a few minutes early and take seats so that you have no immediate neighbors.
    • This is a closed book exam. However, you are allowed to bring FIVE pages (8.5in x 11in), single-sided notes.
    • This test will cover everything covered in lecture all semester! This is a comprehensive exam including the topics of Logic (see Digital Logic Lecture Notes), MOSFET loadline, and MOSFET Q-point (bias circuit) analysis. No MOSFET (CMOS) logic or MOSFET small signal analysis will be on the test.
    • No electronic devices, i.e. calculators, cell phones, computers, etc.
    • SHOW all the steps on the exam. Answers without steps will be given only a small percentage of credits. Partial credits will be given if you have proper steps but no final answers.
    • Remember to put down units. Points will be taken off for answers without units.


    12/10/07

  • HW10 Solutions have been posted.
  • Lecture notes from last Friday on MOSFETs have been posted.
  • Exam topics - Everything covered in lecture all semester! This is a comprehensive exam - the material on the 4 midterms plus the topics covered in lecture since the last midterm - Logic (see Digital Logic Lecture Notes), MOSFET loadline, and Q-point analysis. No MOSFET (CMOS) logic or MOSFET small signal will be on the test.
  • Just a reminder that the review session is tomorrow (Tuesday) 10am-1pm in 4 LeConte.

    12/09/07

  • Tomorrow's lecture is canceled. We will still have the project competition from 4-5 in 247 Cory.

    12/08/07

  • If you are planning to enter the final project competition on Monday, please email Chris (cchase AT eecs DOT berkeley DOT edu) with your name and your partner's so that we know how many projects to expect.
  • Since many students have been asking, the procedure we will use to drop your lowest test score is: The test scores of the 4 midterms will be shifted such that they all have the same mean. The lowest of those 4 shifted scores will be dropped.

    12/06/07

  • You need to have your project circuit checked-off by a TA to get full credit on the project. An additional lab session will be held on Monday 2-4, if you still need to have your project checked off. A hard copy of the lab report for the project will be due on Monday at 5 pm to the drop box in 240 Cory.

    12/05/07

  • We will be giving prizes to the lab section winning the midterm average on Friday. The prize is a green laser pointer. You must be there on Friday in class to get the award!

    12/04/07

  • Project Competition Announcements
    • The project competition will be held on 12/10 (next Monday!) 4-5pm in 247 Cory.
    • Each group will make a 3 minute presentation (either with or without powerpoint is fine) explaining the circuits and another 3 minutes demonstrating the circuits.
    • The final project competition is judged based on the following three categories:
      • Circuit functionality - demonstration of a working circuit at the competition
      • Presentation clarity - explanation of the design and the functions, and the motivations of the design
      • Design creativity and difficulty - ideas beyond the project guideline and textbook knowledge

If you are able to switch out of any of these 3 sections into one of the other sections, please email the GSI of your current section and the GSI of the other section you can to move into. The GSIs email addresses and section times are here. Moving into one of the other sections will help you get in and out of lab faster as you will be vying with fewer students for one TA. It will also prevent us from having to kick anyone out of a lab.
