66.4.3. Gain Considerations

Try these first

1. 1.

   What defines voltage gain in an amplifier?

   Hint

   Think about the basic formula of gain.

2. 2.

   Name one benefit of using active loads.

   Hint

   Consider how they affect performance.

3. 3.

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

   • Lower production cost
   • Increased voltage gain
   • Better sound quality

   Hint

   Consider how they interact with the amplifier’s characteristics.

4. 4.

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

   • True
   • False

   Hint

   Reflect on the general performance of both configurations.

5. 5.

   Design a two-stage amplifier using both CE and CS configurations with active loads. Include biasing methods and calculate the overall gain.

   Hint

   Focus on ensuring stability and linearity in your design.

6. 6.

   Evaluate the impact of temperature changes on the performance of an amplifier using passive versus active loads.

   Hint

   Consider thermal voltage and drift in performance.
