59.2.4. Cascading CS Stage with Common Drain Stage

Try these first

1. 1.

   What is the voltage gain of the common source amplifier discussed in this section?

   Hint

   Refer to parameters like transconductance.

2. 2.

   What is the upper cutoff frequency for the common source amplifier?

   Hint

   Consider the load capacitance used in calculations.

3. 3.

   What is the voltage gain of a typical common source amplifier?

   • 3
   • 6
   • 12

   Hint

   Think about the transconductance value.

4. 4.

   Does the addition of a common drain stage improve input resistance?

   • True
   • False

   Hint

   Recall the properties of the common drain configuration.

5. 5.

   Design a circuit using a common source and common drain stage. Present the voltage analysis showing how the output is derived and calculate the overall expected gain.

   Hint

   Reference the numerical values presented in the examples.

6. 6.

   Assuming biasing changes for the first stage alters the upper cutoff frequency, analyze how these changes impact the overall performance.

   Hint

   Consider referencing how bias stabilization influences the gain and bandwidth.
