LABORATORY EXPERIMENT - The Instrumentation Amplifier

AIM

To improve the understanding of the operation of differential amplifier and the concept of common mode rejection ratio (CMRR).

ANALYSIS AND DISCUSSION

Determine the differential-mode gains, common-mode gains and CMRRs from your experimental data. Compare the experimental results with the calculated results from theory and discuss the possible causes of the difference.

Inspect the changes of differential-mode gains, common-mode gains and CMRRs with the resistor RG. Discuss your observations.
