Question 1.
What is the primary purpose of a common gate amplifier?
Show hintHide hint
Think about what amplifiers primarily do.
Question 2.
Define voltage swing.
Show hintHide hint
Consider how much the output can change.
3Question 3.
What defines a common gate amplifier?
- It has a common source
- It is a series connection
- It has a common gate terminal
Show hintHide hint
Think about how this configuration is named.
4Question 4.
True or False: The voltage gain of a common base amplifier is usually low.
- True
- False
Show hintHide hint
Recall the context of how gains are evaluated.
Question 5.
Design a common gate amplifier that can achieve a 6 V output swing with a 12 V supply while maintaining a 250Ω input impedance. What steps would you follow?
Show hintHide hint
Start from the maximum values and work towards the configurations.
Question 6.
Evaluate the performance alteration in a common base amplifier when the input impedance is altered to 1000Ω. How does this impact overall gains?
Show hintHide hint
Think about how gains interact with impedance.
