   Consider the key advantages we discussed in class.

4. 4.

   The Miller Effect increases what type of capacitance?

   • True
   • False

   Hint

   Think about how feedback loops modify performance.

5. 5.

   You have a Cascode Amplifier circuit with a bias current of 2 mA and an active load of 5 MΩ. Derive the voltage gain and analyze how a lower load resistor would affect the gain.

   Hint

   Understand the relationship between load resistance and voltage gain.

6. 6.

   Explain the trade-offs involved when designing a Cascode Amplifier, focusing on gain and input capacitance. Make diagrams if necessary.

   Hint

   Consider how each design choice influences amplifier performance.
