Course Description

Provides an introduction to semiconductor devices. Characteristics and biasing of diodes and transistors. Covers the 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. 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

Upon successful completion of the course students should be able to:

  1. Analyze circuits using semiconductor device fundamentals.
  2. Use computer tools in circuit evaluation and analysis.
  3. Evaluate and analyze circuits using computer tools.
  4. Write technical project reports.

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
