64.1.6. Part B

Try these first

1. 1.

   What is a cascode amplifier?

   Hint

   Think of how multiple transistors are used together.

2. 2.

   Define the Miller effect.

   Hint

   Consider how capacitance interacts with voltage in amplifiers.

3. 3.

   What is the key advantage of a cascode amplifier?

   • Lower Gain
   • Increased Bandwidth
   • Higher Input Capacitance

   Hint

   Think about the configuration and its influence on signal integrity.

4. 4.

   True or False: The Miller effect results in reduced capacitance in a circuit.

   • True
   • False

   Hint

   Consider how output variations create correlated effects on input capacitance.

5. 5.

   Design a cascode amplifier to be used in an audio application. Discuss the components used and justify each choice.

   Hint

   Consider trade-offs between gain and bandwidth.

6. 6.

   Given an output resistance of 2.6 kOhm and an input capacitance of 10 pF how would you calculate the amplifier's cutoff frequency?

   Hint

   Remember the relationship between frequency, resistance, and capacitance.
