Challenge Problems
Push your limits with challenges.
Question 1
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).
💡 Hint: Remind yourself how to find CMRR from the defined gains.
Question 2
In a scenario where the common mode gain becomes significantly high, discuss the potential impact on the signal output and suggest troubleshooting strategies.
💡 Hint: Consider the factors affecting performance in differential amplifiers.
