Course Description

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.

Course Outcomes

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

  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.
  3. Troubleshoot and repair op-amp circuits.
  4. Write technical reports using collected experiment data.
  5. Identify types of op-amp circuits and determine their function in a circuit.

Suggested 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.

Course Content

  1. Discrete transistor differential amplifier biasing and amplification.
  2. Ideal operational amplifier, inverting and non-inverting amplifier configurations.  Biasing and offset currents, and offset voltages. Feedback theory, and negative feedback in op-amp circuits.
  3. Frequency response, gain-bandwidth product, slew rate, compensation and stability.  Op-amp specifications.
  4. Applications include: voltage summation, subtraction, scaling, voltage and current sources, wave shaping, integration, and differentiation.
  5. Op-amp oscillators and the Barkhausen criterion.  Oscillator types include: RC-phase shift, Wien bridge, Colpitts, and Hartley.        
  6. Active filters concepts and design, including low pass, high pass, and band pass types.
  7. Voltage comparators, Schmitt triggers, and relaxation oscillators, clippers, clampers, rectifiers, and other applications as time permits.
