Think about the purpose of these amplifiers.
4Question 4.
True or False: The common mode gain should be ideally as high as possible in a differential amplifier.
- True
- False
Show hintHide hint
Consider the role of common mode gain.
Question 5.
Given a differential amplifier with inputs of 200 mV and 400 mV, calculate the output if the differential gain is 25 and there’s a common mode gain of 0.1 on a 1 V input. Calculate the total output.
Show hintHide hint
Separate calculations for differential and common mode outputs.
Question 6.
Describe the effects of high common mode gain on the differential amplifier output when attempting to amplify a 50 mV differential input.
Show hintHide hint
Think about how noise interacts with signal amplification.
