Question 1.
Define Common Mode Gain in the context of differential amplifiers.
Show hintHide hint
Think of how the output changes with same input signals.
Question 2.
What does the DC Operating Point represent?
Show hintHide hint
Consider the active region of transistors.
3Question 3.
What does the common mode gain reflect?
- Only differential signals
- Identical signals at both inputs
- Zero signals
Show hintHide hint
Relate it to how outputs change with similar input signals.
4Question 4.
True or False: Large signal analysis focuses only on the AC components.
- True
- False
Show hintHide hint
Think of how we consider total input signals.
Question 5.
Given a differential amplifier circuit with specified resistances and supply voltage, determine the DC operating point and average output swing.
Show hintHide hint
Work through each component, ensuring both transistors stay within their active range.
Question 6.
Discuss the impact of varying the common mode voltage on the DC operating point and the amplifier's performance.
Show hintHide hint
Consider the thresholds for both transistors and how they interact with applied voltage.
