Question 1.
What is the common mode output?
Show hintHide hint
Think about the behavior of outputs when inputs match.
Question 2.
Define common mode gain (Ac).
Show hintHide hint
Consider how amplifiers react to the same input signal.
3Question 3.
What happens to the outputs of a differential amplifier when identical signals are applied to both inputs?
- They will be different
- They will be similar
- One will be zero
Show hintHide hint
Consider how identical inputs affect outputs.
4Question 4.
True or False: Common mode gain is crucial for understanding an amplifier's response to single input signals.
- True
- False
Show hintHide hint
Why is common mode gain relevant?
Question 5.
Assuming you have a common mode voltage of 1.2V. Calculate the effective output voltage if both inputs of the differential amplifier are increased to 2.5V while maintaining identical phase.
Show hintHide hint
Look at how common mode adds to output levels.
Question 6.
Provide an in-depth analysis of how increasing common mode voltages affects both the differential output and operational limits.
Show hintHide hint
Consider the output limits set by DC and common inputs.
