Course Description: Lecture 3 hours, Laboratory 0 hours. Theory, characteristics and operation of diodes, bipolar junction transistors and MOSFET transistors; analog and digital electronic circuits; design and analysis of analog electronic circuits such as filters, operational amplifiers, single and multistage amplifiers; modeling and simulation using spice/multisim software.

Prerequisite: ES 220 and 221 and corequisite: ES 231 (Electronics Lab) or consent of Instructor.

Course Objectives:

·         The ability to analyze and design circuits using operational amplifiers, diodes, MOS transistors, bipolar junction transistors (BJTs).

·         The ability to analyze and design single and multistage amplifiers.

·         Reinforce theory and techniques taught in the classroom through experiments and projects in the laboratory.


Textbook: Microelectronic Circuits by Sedra and Smith, 6th ed., Oxford University Press, ISBN 9780195323030


Course Slides & Preparation: We will go through the course slides based on the textbook, ed. 6 (See the table below) in the class. I urge you to download & review the slides before each class. If you can, make a paper copy and bring it to class to add your notes. You are required to read the textbook after each class for further reinforcement & solve the homework problems. The text includes many examples and exercises with answers in each chapter. Go through the examples and solve the exercises before you solve the homework problems.


Attendance: Attendance is mandatory. There will be no excused absences except in the case of emergencies that could be substantiated. Any absence can affect your learning and your grade.


Class Participation: I highly encourage to participate in the class by asking questions based on the reading and understnding.



·       Homework will be assigned periodically. See the tentative list of activities below.

·       Your solutions & answers must be turned in hard copy no later than the beginning of the class on the specified date.

·       Be concise, neat, & organized with clear explanation. There will be points for your presentation.

·       Please use Microsoft Word for your homework submissions and present the tables and graphs neatly.

·       Failing any of the above, a submission may not be accepted resulting in the loss of grade in that assignment.


Grading Policy:

·        Attendance, in-class participation, quizzes                                                     10%

·        Homework assignments (no later than due time)                                          20%

·        Test #1 (1 hour, see date below)                                                                        20%

·        Test #2 (1 hour, see date below)                                                                        20%

·        Final Exam (2 hours, see date below)                                                               30%

·        For final grades the university grading system (A = 94 and above, A- = 90-93, B+ = 87-89, B =84-86, B- =80-83, C+ =77-79, C- =74-76, C- =70-73, D+ =67-69, D = 64-66, D- = 60-63, F = below 60) may be used.


Deadlines to drop the course: Please refer to the university calendar ( for drop with W, etc.


My Expectations:

·         Always come to class prepared & on-time to learn.

·         Whenever for some critical reason you cannot attend, send me an email in advance.

·         Pay 100% attention. No talking is allowed.

·         Turn off cell phones, earphones and other distracting devices.

·         Read the slides before each lecture and the related chapter after the lecture. Also, reading the references deepens your understanding as a student.

·         Hand in your assignments on time at the beginning of the class.

·         Speak up whenever you have questions or suggestions & contribute when you can.

·         Have fun & look back on this as a positive & worthwhile course for your study & career development.
