Amplifiers

In this lab, students will explore, through hands-on experience, the properties of open-loop op amps and closed-loop amplifier configurations. Students will measure and compare the input and output states of inverting, non-inverting, unity gain, and instrumentation amplifiers. Student will calculate expected gain values for different resistance configurations, and will measure the effect of an output load on unity gain and instrumentation amplifiers.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Simulate open-loop gain using an operational amplifier
  2. Calculate expected gains for amplifier topologies
  3. Simulate and measure amplified signals
  4. Experiment with resistances to modify amplifier gains
  5. Measure the current draw from unity gain and instrumentation amplifiers
 

REQUIRED SKILLS

 
  • Basic proficiency using Multisim Live and LabVIEW
  • Basic proficiency using ELVIS III Instruments
  • Basic knowledge of components and their behaviors

NI ELVIS III

Engineering laboratory solution for project-based learning that combines instrumentation and embedded design with a web-driven experience, delivering a greater understanding of engineering fundamentals and system design.

Automated Measurements Board for NI ELVIS III

An application board for NI ELVIS III that provides students with a experimental platform for understanding and designing a signal chain for sensor integration.

LabVIEW

LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights.

Multisim Live

Multisim Live is an online, touch-optimized component of Multisim, so students can design and simulate their circuits anywhere, anytime, on any device.
