Question 1.
What is a cascode amplifier?
Show hintHide hint
Think about the structure of the amplifier.
Question 2.
Explain the Miller effect briefly.
Show hintHide hint
Focus on how the amplifier's gain affects capacitance.
3Question 3.
What does a cascode amplifier primarily increase?
- Gain
- Bandwidth
- Input Capacitance
Show hintHide hint
Consider the primary function of the amplifier.
4Question 4.
True or False: Increasing resistance in a cascode amplifier will always improve bandwidth.
- True
- False
Show hintHide hint
Think about the effects on frequency response.
Question 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.
Show hintHide hint
Consider bandwidth implications and the appreciated Miller effect.
Question 6.
Build a scenario where you need to use a cascode amplifier versus a single CE amplifier. What factors will determine the best choice?
Show hintHide hint
Remember to weigh the trade-offs.
