Examines the characteristics and applications of operational amplifiers (op-amps). Develops skills in the design and analysis of op-amp amplifiers, comparators, voltage and current regulators, summers, integrators, and differentiators. Covers calculation and analysis of frequency response of op-amp circuits and application of the op-amp in power supplies and control systems. Includes a 3-hour per week laboratory in project design, evaluation, documentation, and use computer tools. Prerequisites: EET 221. Audit available.
Upon successful completion of this course, students will be able to:
- Apply op-amps fundamentals in design and analysis of op-amps applications.
- Apply op-amps fundamentals and computer tools in project design, evaluation, and analysis.
- Troubleshoot and repair op-amp circuits.
- Write technical reports using collected experiment data.
- Identify types of op-amp circuits and determine their function in a circuit.
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
Lecture and discussion are the instructional methods used. Weekly homework is assigned. Laboratory activity includes building circuits on solder-less breadboards, making circuit measurements using test equipment, analyzing test data, comparing predictions to theory.
Lab exercises also involve using a PC with spreadsheet, word processor, and circuit simulation software.
