Course DescriptionIntroduction to semiconductor devices. Characteristics and biasing of diodes and transistors. Design and analysis of circuits using diodes, bipolar transistors, and field effect transistors. Application of transistors as amplifiers and switches. A 3-hour per week laboratory includes the application of computer tools in circuit design, evaluation, and analysis. Prerequisites: EET 113, MTH 112. Audit available.
Addendum to Course Description
In addition to introducing the basic theoretical principles of operation of diodes and transistors, the operational characteristics of the devices will be studied, and measured using curve tracers, simulation, and computer data acquisition methods. This term emphasizes diode and transistor biasing circuits, and basic transistor amplifier circuits.
Intended Outcomes for the course
1. Apply concepts of semiconductor devices to design and analyze circuits.
2. Apply fundamentals of semiconductor devices in electronics projects and use computer tools in circuit design, evaluation and analysis.
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
