66.3. Recapitulation of CE Amplifier

Try these first

1. 1.

   What is the function of the collector resistor in a CE amplifier?

   Hint

   Think about how the CE amplifier operates.

2. 2.

   Define voltage gain.

   Hint

   Consider how an amplifier enhances a signal.

3. 3.

   What does the collector resistor in a CE amplifier do?

   • It stabilizes the voltage
   • It converts current to voltage
   • It increases input signal
   • It decreases noise

   Hint

   Think about the roles of components in an amplifier circuit.

4. 4.

   True or False: The voltage gain of a CE amplifier can be increased indefinitely by raising the supply voltage.

   • True
   • False

   Hint

   Consider the physical limitations of electronic components.

5. 5.

   If a CE amplifier has a limited gain due to a passive load, how could you express the steps mathematically to improve its gain using an active load? Develop a circuit schematic to illustrate your approach.

   Hint

   Focus on how changing R_C to R_load modifies gain in practical scenarios.

6. 6.

   Devise a comparative analysis between voltage gain in CE amplifiers with passive loads versus active loads. Use numerical values to support your points, reflecting real-world applications.

   Hint

   Reflect on gain improvements while maintaining device stability.
