Question 1.
What is the role of differential gain in a differential amplifier?
Show hintHide hint
Think about the key function of the circuit.
Question 2.
Define common mode gain.
Show hintHide hint
Recall its role in mixture signals.
3Question 3.
What does differential gain refer to?
- Amplification of common signals
- Amplification of the difference between two signals
- Amplification of noise
Show hintHide hint
Focus on the definition of terms.
4Question 4.
If both common mode gains are non-zero, what is likely to happen to the output?
- True
- False
Show hintHide hint
Consider the impact of additional signals.
Question 5.
Consider a differential amplifier with a differential gain of 60 and a common mode gain of 0.3 if the differential input signal is 80 mV. What is the expected output with calculations?
Show hintHide hint
Use both the differential gain and common mode gain in your calculations.
Question 6.
Analyze the impact of increasing the common mode gain to 1.5 in the above scenario. How does it affect overall output?
Show hintHide hint
Pay careful attention to the rise in unwanted components.
