Question 1.
What does a differential amplifier amplify?
Show hintHide hint
Think about the context where two signals need to be compared.
Question 2.
In which mode do the inputs receive the same signal?
Show hintHide hint
Consider situations where sources are not different.
3Question 3.
What happens to the output when both differential inputs are equal?
- True
- False
Show hintHide hint
Remember the behavior of differential amplifiers under equal input conditions.
4Question 4.
The differential mode gain is defined as which ratio?
- Output Voltage Difference / Input Voltage Difference
- Input Voltage Difference / Output Voltage Difference
- Output Voltage / Common Voltage
Show hintHide hint
Think about how these voltages relate in amplification.
