Question 1.
What is the primary voltage swing achievable in a common gate amplifier if the supply voltage is 12V?
Show hintHide hint
Consider the relationship between supply voltage and output swing limits.
Question 2.
Define the output swing in the context of an amplifier.
Show hintHide hint
Think about how the minimized and maximized values are set by the supply voltage.
3Question 3.
What is the output voltage swing limitation of a common gate amplifier connected to a 12 V source?
- ±12 V
- ±6 V
- ±4 V
Show hintHide hint
Think about the power supply constraints.
4Question 4.
True or False: The input impedance of an amplifier does not affect the performance of the preceding circuit.
- True
- False
Show hintHide hint
Consider the impact of current draw on neighboring circuits.
Question 5.
Design a circuit that satisfies a ±4 V output swing but also requires a voltage gain of 10. Propose resistor choices and justification.
Show hintHide hint
Start from basic gain formulas in small signal analysis.
Question 6.
Examine the effects of feedback on a common base amplifier and how it alters current gain. Provide a theoretical approach to support your argument.
Show hintHide hint
Think about how feedback enhances or diminishes signal integrity.
