Question 1

What is the purpose of cascading amplifiers?

  • To decrease bandwidth
  • To increase the overall gain
  • To isolate circuits
  • To modify frequency response

💡 Hint: Think about the main goal of connecting multiple amplifier stages.

Question 2

True or False: Cascading two amplifiers inevitably results in a gain that is the product of their individual gains.

  • True
  • False

💡 Hint: Consider what might affect the actual performance.

Challenge Problems

Push your limits with challenges.

Question 1

Design a scenario in which you need to cascade two common emitter amplifiers; what challenges might arise, and how would you use buffers to solve them?

💡 Hint: Consider each amplifier's specifications when discussing potential gains and bandwidth.

Question 2

Consider a circuit with a CE amplifier with gain A1 = 10, cascaded with another CE amplifier with gain A2 = 5, experiencing 30% loss due to loading effects. Calculate the effective gain.

💡 Hint: Remember to apply the loss factor after calculating the initial product gain.
