Try these first

1. 1.

   What is the primary function of a common collector amplifier?

   Hint

   Think about the voltage relation entering and leaving the amplifier.

2. 2.

   How does adding a load resistance affect voltage gain?

   Hint

   What happens to voltage when it's divided?

3. 3.

   What is the role of a common collector amplifier?

   • Voltage amplification
   • Current buffering
   • Voltage buffering

   Hint

   Think about its impedance characteristics.

4. 4.

   True or False: The input resistance of a common collector amplifier is low.

   • True
   • False

   Hint

   Recall what high input resistance means in circuit terms.

5. 5.

   Given a common collector amplifier with a load resistance of 15kΩ and bias resistance of 5kΩ. Calculate the output voltage if the input is 5V.

   Hint

   Use the properties discussed regarding voltage gain.

6. 6.

   For a common drain amplifier with losses from gate to source capacitance due to high frequency operation, how would this affect overall voltage gain?

   Hint

   Consider the effects of capacitors in AC considerations.
