4. Instructor Availability Instructor: Dr. Jack Ou Office: Salazar 2010B Office hours: – MW 10:30-11:00, TH 3:00 to 4:00 Email: jack.ou@sonoma.edujack.ou@sonoma.edu – I like to communicate over email. – I do not check my voice mail. Do not overlook the opportunity to meet with the instructor.

5. Prerequisite: Electric Circuits (ES220) Concepts from ES220 – Ohm’s law – Series/parallel circuit – Voltage/current divider – Nodal analysis – Mesh analysis – Dependent sources – Thevenin and Norton Equivalent Circuit – AC analysis

6. Prerequisite: Physics 214 Need to tie substrate to GND to avoid current through PN diode. Positive charges repel the holes creating a depletion region, a region free of holes. Free electrons appear at V G =V TH. V TH =300mV to 500 mV (OFF)(ON)

7. Lessons from Electronics I Diode – Device Physics – Circuit Design Bipolar junction transistor – Device Physics – Circuit Design Complementary Metal Oxide Semiconductor – Device Physics (STOPPED HERE!) – Circuit Design (NAND Gate)

8. BJT & MOS Transistor [Chapter 4,5] [Chapter 6,7]

9. Analogous Devices Terminals – “C”↔”D” – “E” ↔”S” – “B” ↔”G” Analogous Devices – NPN ↔NMOS – PNP ↔PMOS

10. Equivalent Circuit

11. Small Signal Model (NPN)(PNP) Statements that are always true for both NPN and PNP. 1.r π is between B and E. 2.the direction of the dependent current source always points from the collector to emitter. 3. r o is always between B and C.

12. Small Signal Analysis 1.Replace each ideal DC voltage source with a small signal ground. 2.Replace each ideal DC current source with an open circuit. 3.Replace each transistor by its small signal model 4.Analyze the small signal equivalent circuit.

13. Voltage Source Replace the DC voltage Source with a short to ground. R S should be ~0 for a good battery!

14. Current Source R S should be infinity for a good current source!

15. Terminal Resistance of a BJT Eq. 5.162 Eq. 5.198 Eq. 5.291

26. Textbook Required Text: Behzad Razavi, “Fundamentals of Microelectronics”, Wiley, 1 st edition. (ISBN-13: 978-0-471- 47846-1) Reminder: ES330 is a 2-unit course requiring an average of 6-8 hours of study per week!

27. Course Policies Regarding classroom conduct Regarding homework, exams and Piazza

28. Grading Three exams – (total: 40 %. Exam #1=20 %, final=20 %) Class participation – (total: 10 %. Attendance=5%, participate in active learning exercises both in class and out of class=5%) Supplemental assignments – (total: 5 %. Supplemental assignments consist of videos, articles, and other forms of exercises design to stimulate students’ interest in semiconductor industry) Homework assignment: – 25 % Project – 20%

29. Classroom Participation Examples of exercises – You are given a blank sheet of paper, and asked to respond a brief question. You will not be graded. – You maybe asked to present the solution you have worked on in class. – You maybe asked to summarized other students’ response – You maybe asked to complete anonymous survey about the course

30. Supplemental Assignment Focus – History of Silicon valley – Engineers’ reflection of their career – Talks given by some interesting characters Format: video/articles

31. Homework 20 % of the final grade – Problems in each assignment are graded selectively. – Effort based. – Each assignment can take on an average six hours to complete – Please start your assignment early. Do not wait till the last minute – Post your questions on Piazza

32. Homework Tips Try to attack the problems from different angles – Ask the what if questions Summarize the question in your own words. “I am stuck because …..” “This problem frustrates me because….” “Here is what I do not understand…..” “Here is what I know about this problem….” Be self-critical. Be suspicious of assumptions that you considered to be true. Be disciplined. If you are truly stuck, move on and come back to work on the question.

33. Helpful practices for better grades Before class – Download the lecture notes from the website and review them – Make a list of questions that you want to ask – Make use of instructor’s office hour In class – Stay awake and listen actively – Participate in exercises – Take notes. Make a mental list on what is confusing to you. After class – Set aside a time to study. – Review the notes. Use the textbook as a reference. – Do assignments/homework before the deadline – Post questions on Piazza

34. Important Dates 9/3 last day to drop a course with adjusted fees (done on-line) 9/4-15: drop with a “W” (done on-line) 9/16-11/13: petition to withdraw from a class with $20 administrative fee (dropping classes permitted because of serious and compelling reasons)
