49.2. Discussion on Common Base and Common Gate Amplifiers

Try these first

1. 1.

   What is the role of the common base amplifier?

   Hint

   Think about how the terminals relate in this configuration.

2. 2.

   Define what biasing means in amplifiers.

   Hint

   Why do amplifiers need to be set to a certain level?

3. 3.

   What is the primary function of a common base amplifier?

   • A) Voltage amplification
   • B) Current amplification
   • C) Both voltage and current amplification

   Hint

   Think about the configurations discussed in class.

4. 4.

   True or False: In a common gate amplifier, the input impedance is high.

   • True
   • False

   Hint

   Recall the impedance characteristics we discussed.

5. 5.

   Design a common base amplifier with specific DC biasing conditions. Outline the components required and their values.

   Hint

   Consider the necessary specifications for your DC levels.

6. 6.

   Analyze the frequency response of a common gate amplifier and report how loading on the output impacts the gain.

   Hint

   Refer back to our discussion on loading effects and impedance analysis.
