1. 1.

   What is the primary function of a common base amplifier?

   Hint

   Consider its configuration with respect to other amplifiers.

2. 2.

   Name the two types of transistors used in common base and common gate amplifiers.

   Hint

   Think about the fundamental components in electronics.

3. 3.

   Which configuration is suitable for BJT transistors as a buffer?

   • Common Base
   • Common Emitter
   • Common Collector

   Hint

   Recall the key features of BJT configurations.

4. 4.

   True or False: The output of a common gate amplifier is in phase with its input.

   • True
   • False

   Hint

   Think about how the signals flow through the amplifier.

5. 5.

   Design a common base amplifier circuit for a specific gain and input impedance. Provide calculations for the required component values.

   Hint

   Use small signal analysis to guide your calculations.

6. 6.

   Evaluate the impact of a heavy load connected to the output of a common gate amplifier on its performance. What measures can be taken to mitigate this?

   Hint

   Consider how impedance matching can influence your design.
