65.1.7. Gain Comparison with Common Source Amplifier

Try these first

1. 1.

   What is the key difference in gain between a common source amplifier and a cascode amplifier?

   Hint

   Think about how active loads impact performance.

2. 2.

   Define transconductance.

   Hint

   It's a crucial parameter in amplifiers.

3. 3.

   What is the gain of a typical common source amplifier?

   • 1
   • 4
   • 10
   • 100

   Hint

   Recall the basic characteristics of a common source amplifier.

4. 4.

   True or False: A cascode amplifier can achieve higher gain than a common source amplifier.

   • True
   • False

   Hint

   Think about the active load advantages.

5. 5.

   Given a Cascode amplifier with resistances of 5 MΩ and transconductance of 3 mA/V, calculate the voltage gain and discuss how this would affect bandwidth.

   Hint

   Remember: Voltage Gain = Resistance × Transconductance.

6. 6.

   Analyze a circuit that includes a cascode amplifier versus a common source amplifier under varying load conditions. How do the performance metrics change?

   Hint

   Consider the operational advantages of each configuration!
