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.
