Course Description

Examines the characteristics of semiconductor devices and biasing of diodes and transistors. Covers design and analysis of semiconductor circuits using diodes, bipolar transistors, field effect transistors, SCR’s, MOSFET’s, and IGBT’s.  Covers use of transistors as switches. Includes 3 hour lab that explores the application of semiconductor devices, configurations, and computer tools in circuit design, evaluation, and analysis. Prerequisite: EET 113. Audit available.

Intended Outcomes

Upon successful completion of this course, students will be able to:

  1. Apply concepts of semiconductor devices, diodes and transistors, to design and analyze circuits.
  2. Apply fundamentals of semiconductor devices in electronics projects and use computer tools in circuit design, evaluation, and analysis.
  3. Write technical reports using collected experiment data.
  4. Apply concepts of semiconductor devices to troubleshoot circuits.
  5. Apply concepts of semiconductor devices in problem solving.

Outcome Assessment Strategies

Assessment methods are to be determined by the instructor. Typically, in class exams and quizzes, and homework assignments will be used. Lab work is typically assessed by a lab notebook, formal lab reports, performance of experiments, and possibly a lab exam.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.
