Question 1.
What is the primary function of a common drain amplifier?
Show hintHide hint
Think about how it relates to input and output voltage.
Question 2.
Why is high input resistance important?
Show hintHide hint
Consider what happens when too much current is drawn.
3Question 3.
What is the approximate voltage gain of a common drain amplifier?
- 0.5
- 1
- 1.5
Show hintHide hint
Think about its role as a voltage follower.
4Question 4.
Does a high input resistance benefit a common drain amplifier?
- True
- False
Show hintHide hint
Remember why we want to avoid drawing too much current at the input.
Question 5.
Given a common drain amplifier with an input capacitance of 10 pF and a load resistance of 1kΩ, calculate how the Miller effect alters the effective input capacitance.
Show hintHide hint
Remember the formula takes into account the feedback effect.
Question 6.
Design a common drain amplifier circuit that can operate effectively with a certain range of frequencies. Discuss the selection of components.
Show hintHide hint
Think about how impedance and frequencies interact.
