59.5. Summary

Try these first

1. 1.

   What is the voltage gain of a Common Source amplifier with a transconductance of 2 mA/V and a load resistance of 3 kΩ?

   Hint

   Use the formula A_v = g_m * R_D.

2. 2.

   What is the role of the upper cutoff frequency in amplifier design?

   Hint

   Think about where the output power drops significantly.

3. 3.

   What is the voltage gain of a Common Source amplifier with a transconductance of 2 mA/V and load resistance of 3 kΩ?

   • 2
   • 4
   • 6
   • 8

   Hint

   Remember the gain formula.

4. 4.

   True or False: Cascading enhances the bandwidth of amplifier circuits.

   • True
   • False

   Hint

   Think about the implications of connecting multiple stages.

5. 5.

   Design a multistage amplifier circuit using a Common Source followed by a Common Drain stage. Calculate the expected overall gain and upper cutoff frequency.

   Hint

   Break it down to calculate gain and bandwidth stage by stage.

6. 6.

   If a Common Source amplifier circuit shows a voltage gain of 10 but the upper cutoff frequency is too low, what modifications could you suggest?

   Hint

   Think about the elements that can be adjusted or added to enhance performance.
