Question 1.
Define 'common gate amplifier'.
Show hintHide hint
Think about the terminal connected to both input and output.
Question 2.
What is the role of a coupling capacitor in the amplifier?
Show hintHide hint
Focus on what signals it filters out.
3Question 3.
What effect does a coupling capacitor have in a common gate amplifier?
- Blocks AC signals
- Allows AC signals to pass
- Increases DC voltage
Show hintHide hint
Think about the types of signals flowing through.
4Question 4.
Removing the coupling capacitor increases input resistance by a factor of:
- True
- False
Show hintHide hint
Remember the factor of ten discussed.
Question 5.
A R60k ohm input resistance is given in a common gate amplifier without a capacitor. Describe the possible effects on performance and signal integrity.
Show hintHide hint
Reflect on factors that can affect the efficiency of circuit performance.
Question 6.
Calculate the voltage gain of a common gate amplifier if the input and output resistances are affected by missing components. Derive the formula based on the provided parameters.
Show hintHide hint
Start with the fundamental gain equation and modify accordingly.
