50.1.1. Current Gain Analysis

Try these first

1. 1.

   What does the term 'current gain' mean?

   Hint

   Think about how an amplifier boosts signals.

2. 2.

   Define common base configuration.

   Hint

   Focus on which terminal is shared in the setup.

3. 3.

   What is the current gain of a common gate amplifier under ideal conditions?

   • 0.5
   • 1
   • 2

   Hint

   Consider how much input current actually goes to output.

4. 4.

   True or False: The common base configuration has a high input resistance.

   • True
   • False

   Hint

   Think about how the input interacts with the transistor.

5. 5.

   Design a common base amplifier circuit with specified values for resistances, and determine the current gain under loaded conditions.

   Hint

   Consider each component's influence on total resistance and current.

6. 6.

   Analyze how changing biasing arrangements in a common gate circuit affects the output current versus input current relationship.

   Hint

   Look into varying resistor values and their proportional output changes.
