Try these first

1. 1.

   What is a cascode amplifier?

   Hint

   Think about how stacking can help with signal strength.

2. 2.

   Define gain in the context of amplifiers.

   Hint

   Consider how much stronger the output is compared to the input.

3. 3.

   What is a key advantage of a cascode amplifier?

   • A) Reduced gain
   • B) Improved bandwidth
   • C) Lower input resistance

   Hint

   Think about why we'd want a higher frequency range.

4. 4.

   True or False: The Miller effect decreases the input capacitance.

   • True
   • False

   Hint

   Recall how the effect makes capacitance appear larger.

5. 5.

   Design a cascode amplifier with a given input resistance of 5 kΩ and an output load resistance of 10 MΩ. Calculate the expected gain and bandwidth and discuss the influence of the Miller effect.

   Hint

   Consider all forms of resistance and how they impact your design choices.

6. 6.

   Evaluate the performance degradation in bandwidth if the output resistance rises unnaturally high due to component selection in a cascode amplifier. Propose solutions to manage bandwidth.

   Hint

   Think about alternatives to manage high resistance efficiently.
