37.1.2. Common Source Amplifier Circuit

Try these first

1. 1.

   What is the role of a common source amplifier?

   Hint

   Think about what amplifiers typically do.

2. 2.

   What is transconductance?

   Hint

   Focus on how transistors function in amplifying signals.

3. 3.

   What does a common source amplifier primarily do?

   • Increases signal power
   • Modulates frequency
   • Amplifies voltage
   • Filters noise

   Hint

   Think about the amplifier's primary function.

4. 4.

   Thevenin's theorem simplifies circuits. Is this statement True or False?

   • True
   • False

   Hint

   Recall what Thevenin's theorem accomplishes.

5. 5.

   Design a common source amplifier with a target gain of -15. Given that the transconductance is 5mS, find the necessary RD if the input voltage is 2V.

   Hint

   Keep the gain formula in mind and isolate RD.

6. 6.

   Demonstrate how changes in frequency affect the output signal in a common source amplifier with both input and output capacitors. Calculate the impact on gain as frequency varies from low to high.

   Hint

   Explore individual capacitor impacts on gain across frequency ranges.
