Semiconductor Theory

I.     Course Prefix/Number: ELT 106

       Course Name: Semiconductor Theory

       Credits: 3 (2 lecture; 2 lab)

II.    Prerequisite

Recommended: ELT 101

III.   Course (Catalog) Description

Course presents basic study of diodes and transistors. Content includes grounded base, emitter and collector amplifiers; study of stability, gain and the impedance characteristics of the transistor.

IV.   Learning Objectives

Student will learn to:

  1. List the functions of diodes and transistors in AC and DC circuits.
  2. Identify the type of biasing techniques as well as the AC and DC characteristics.
  3. Describe common transistor configurations and design various types of circuits
  4. Use mathematical methods to model and predict the behavior of diode and transistor circuits.
  5. Analyze diode and transistor circuits using computer simulation software.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

VI.   Sequence of Topics

Diode Theory
Diode Circuits
Special Purpose Diodes
Bipolar Junction Transistors
Transistor Fundamentals
AC Models
Voltage Amplifiers
CC and CB Amplifiers

VII.  Methods of Instruction

This course will be one half lecture and class discussion and one half laboratory experimentation.  The lecture will be an informal discussion on the assigned topics and related material.  The lab experiments will be timed to reinforce ideas discussed in the lecture and to learn the operation of the lab equipment.

Course may be taught as face-to-face, hybrid or online course.

VIII. Course Practices Required

Students will study from textbook, take notes, and finish the lab assignments.  Lab work is designed so that it can be completed during normal class hours.  Homework problems will be assigned to reinforce the lecture and text.

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.

X.    Methods of Evaluating Student Progress

Three one-hour exams 80% A = 90-100
Lab experiments 20% B = 80-89
C = 70-79
D = 60-69
F = Below 60
Class attendance is necessary to receive full credit in the above categories.

XI.   Other Course Information

Assignments are due at the next class session. A make-up test may be given if the student has a viable excuse.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.

Oakton Community College is committed to maintaining a campus environment emphasizing the dignity and worth of all members of the community, and complies with all federal and state Title IX requirements.

Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.

For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.

Violation of this policy will result in disciplinary action through the Code of Student Conduct.
