31.1.2. Designing for Lower Gains

Try these first

1. 1.

   What is the maximum gain achievable by a CE amplifier?

   Hint

   Refer back to the section discussing gain limits.

2. 2.

   Why would you want to design for a lower gain?

   Hint

   Think about different use cases for amplifiers.

3. 3.

   What is the maximum gain for a common emitter amplifier?

   • 150
   • 230
   • 300

   Hint

   Refer back to the concepts discussed regarding amplifier gains.

4. 4.

   True or False: Partial bypassing of the emitter resistor increases gain fluctuations.

   • True
   • False

   Hint

   Consider the effect of increased stability on the bias point.

5. 5.

   Design a CE amplifier with a gain of at least 15 using partial bypassing. Explain how the values were chosen to maintain bias stability.

   Hint

   Think about how partial bypassing impacts the bias stability.

6. 6.

   You have two cascade stages both designed for approximately 200 gain. However, after connecting them, the output gain measured is only around 150. What could be the issue?

   Hint

   Consider revisiting the resistance calculations for both stages.
