Question 1.
What is the difference between differential and common mode signals?
Show hintHide hint
Think about how you can characterize the relationship of the two signals.
Question 2.
What should the ideal differential gain be?
Show hintHide hint
Consider what you would want it to amplify.
3Question 3.
What is the ideal expectation for differential gain?
- High
- Low
- Negative
Show hintHide hint
Consider what you want with amplifier output.
4Question 4.
True or False: Common mode gain should be high for best performance.
- True
- False
Show hintHide hint
Reflect on the noise versus signal ratio.
Question 5.
The differential amplifier has the following: A_d = 50, A_c = 2. If you have inputs v_in1 = 5V and v_in2 = 2V, calculate the output and analyze how the gains affect the output quality.
Show hintHide hint
Utilize the formula for both outputs and reflect on the effects of gain levels.
Question 6.
If both differential and common mode gains were to switch roles, what implications would arise for the circuit performance? Discuss in detail.
Show hintHide hint
Consider how gain configurations influence circuit reliability and fidelity.
