Try these first

1. 1.

   What is a cascode amplifier?

   Hint

   Think about the structure of the amplifier.

2. 2.

   Explain the Miller effect briefly.

   Hint

   Focus on how the amplifier's gain affects capacitance.

3. 3.

   What does a cascode amplifier primarily increase?

   • Gain
   • Bandwidth
   • Input Capacitance

   Hint

   Consider the primary function of the amplifier.

4. 4.

   True or False: Increasing resistance in a cascode amplifier will always improve bandwidth.

   • True
   • False

   Hint

   Think about the effects on frequency response.

5. 5.

   Design a cascode amplifier that must function adequately at 1 kHz while sustaining a gain of at least 100. Discuss how you will choose the components involved.

   Hint

   Consider bandwidth implications and the appreciated Miller effect.

6. 6.

   Build a scenario where you need to use a cascode amplifier versus a single CE amplifier. What factors will determine the best choice?

   Hint

   Remember to weigh the trade-offs.
