66.5. Limitations of Gain in CE Amplifier

Try these first

1. 1.

   What is the role of the load resistor in a CE amplifier?

   Hint

   Think about how it aids in voltage conversion.

2. 2.

   Name two types of loads in amplifiers.

   Hint

   One type cannot provide gain by itself.

3. 3.

   What is the primary limitation of voltage gain in a CE amplifier?

   • Supply voltage
   • Collector resistor value
   • Input impedance

   Hint

   Consider how the supply current affects performance.

4. 4.

   True or False: A passive load can provide gain by itself.

   • True
   • False

   Hint

   Think about the definition of a passive component.

5. 5.

   Derive a complete model for a CE amplifier showcasing both active and passive load configurations. Present equations for gain under both scenarios.

   Hint

   Consider how aspects influence both loads’ performance.

6. 6.

   Design a scenario where both CE and CS amplifiers are operational. Highlight how to improve performance by replacing passive components.

   Hint

   Framework designs that leverage the active load benefits.
