Course DescriptionCharacteristics and applications of operational amplifiers (op-amps). Design and analysis of op-amp amplifiers, comparators, voltage and current regulators, summers, integrators, and differentiators. Frequency response of op-amp circuits. Applications of the op-amp in power supplies and control systems. A 3-hour per week laboratory includes project design, evaluation, and documentation. Use of computer tools. Prerequisites: EET 221 Audit available.
Addendum to Course Description
The focus of this term is on operational amplifier characteristics and applications. The laboratory component includes applications such as waveform generator circuits, filters, and instrumentation amplifiers.
Intended Outcomes for the course
1. Apply op-amps fundamentals in design and analysis of op-amps applications.
2. Apply op-amps fundamentals and computer tools in project 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.
Course Content (Themes, Concepts, Issues and Skills)
