66.2.2. Basic Operation of Amplifier with Active Load

Try these first

1. 1.

   What is the main advantage of using active loads in amplifiers?

   Hint

   Think about the definition of active vs passive.

2. 2.

   Define a common emitter amplifier in your own words.

   Hint

   Consider its basic operational principle.

3. 3.

   What is a key advantage of active loads in amplifiers?

   • Lower gain
   • Higher gain
   • No change in gain

   Hint

   Recall the benefits of active devices.

4. 4.

   True or False: Common source amplifiers typically have higher voltage gain than common emitter amplifiers.

   • True
   • False

   Hint

   Consider the practical examples discussed.

5. 5.

   Design a simple common emitter amplifier circuit using active loads. Explain how it improves the voltage gain.

   Hint

   Consider the formulas for gain and how they relate to your circuit choice.

6. 6.

   Evaluate the performance of a common source amplifier with passive loads. How would you modify it to enhance its voltage gain?

   Hint

   Reflect on how load effects influence amplifier operation.
