3 cards from this section. Quick, good the night before a test.
What is the primary purpose of a differential amplifier?
Think of it as a device that focuses on differences.
Why is it important for the common mode gain to be low?
Consider what happens if noise is amplified along with the desired signal.
What is the primary function of a differential amplifier?
Focus on what is amplified.
True or False: The common mode gain should be high for effective performance of differential amplifiers.
Consider the relationship of common mode signals.
Consider a differential amplifier used in a distance sensor system. You're receiving weaker signals due to noise interference. Propose a solution to increase the signal quality.
What types of amplifiers can you suggest that could help?
Critically analyze a scenario where an op-amp with high common mode gain is used. Discuss possible circuit redesigns to prevent issues.
Consider circuit elements that prioritize differential amplification.
