What is a differential amplifier?
Think about why it has two input terminals.
What is the ideal property of differential mode gain?
Consider its role in amplifying signals.
What does a differential amplifier primarily amplify?
Think about the purpose of having two inputs.
True or False: Ideal differential mode gain should be minimized.
Recall the ideal characteristics preferred in amplifiers.
Given a differential amplifier with a measured differential mode gain of 20 and a common mode gain of 0.5, calculate the common mode rejection ratio (CMRR).
Remind yourself how to find CMRR from the defined gains.
In a scenario where the common mode gain becomes significantly high, discuss the potential impact on the signal output and suggest troubleshooting strategies.
Consider the factors affecting performance in differential amplifiers.
