   Hint

   Think about the setup of input and output terminals.

2. 2.

   What do we aim to achieve through biasing?

   Hint

   Consider the importance of voltage and current control in circuits.

3. 3.

   What is the primary function of a common base amplifier?

   • Voltage gain
   • Current gain
   • Power gain

   Hint

   Think about how this amplifier configuration operates.

4. 4.

   True or False: Passive biasing offers better stabilization than active biasing.

   • True
   • False

   Hint

   Recall the definitions of both biasing types.

5. 5.

   Design a common base amplifier circuit and discuss the choice of biasing scheme suitable for low frequency signals.

   Hint
