Try these first

1. 1.

   What is the primary advantage of using multi-transistor amplifiers?

   Hint

   Think about how they handle input and output impedance.

2. 2.

   Name the three basic configurations discussed in multi-transistor amplifiers.

   Hint

   Recall the acronym for these configurations.

3. 3.

   What effect does cascading a common collector stage have on output impedance?

   • Increases
   • Decreases
   • No effect

   Hint

   Consider how impedance changes with additional stages.

4. 4.

   True or False: A common base amplifier excels in voltage amplification.

   • True
   • False

   Hint

   Reflect on the performance parameters for CB configurations.

5. 5.

   Design a cascaded amplifier using CE and CC stages and analyze its performance metrics compared to a standalone CE amplifier.

   Hint

   Examine how cascading affects the individual performance parameters.

6. 6.

   If you had to choose between a CB or CC stage to follow a CE amplifier for current boosting, which would you choose and why?

   Hint

   Reflect on the advantages and limitations of CB and CC in relation to current amplification.
