66.2.1. Motivation of Using Active Load

Try these first

1. 1.

   What is an active load?

   Hint

   Think about the difference between active and passive components.

2. 2.

   Name one advantage of using active loads.

   Hint

   Consider the gain limitations of passive components.

3. 3.

   What is the primary benefit of using an active load in amplifiers?

   • Lower cost
   • Higher voltage gain
   • Less complexity

   Hint

   Think about how gain translates into practical amplifier capability.

4. 4.

   True or False: Active loads can provide improved linearity compared to passive loads.

   • True
   • False

   Hint

   Reflect on the operational regions of active versus passive components.

5. 5.

   Design a common emitter amplifier circuit using both passive and active loads. Compare and analyze the expected output gains from both designs.

   Hint

   Use the gain equation A_v = g_m * R_load to compare actual values.

6. 6.

   Discuss how increasing the temperature affects the performance of both passive and active loads in an amplifier design.

   Hint

   Review how temperature influences electronic materials in both setups.
