Try these first

1. 1.

   What is the voltage gain for a common source amplifier where g = 2 mA/V and R = 3 kΩ?

   Hint

   Use the formula A = g * R.

2. 2.

   Define the term 'transconductance'.

   Hint

   Think about how it measures signal amplification.

3. 3.

   What is the voltage gain if transconductance is 2 mA/V and output resistance is 3 kΩ?

   • 2
   • 4
   • 6

   Hint

   Use the formula A = g * R.

4. 4.

   True or False: The common source amplifier increases output voltage.

   • True
   • False

   Hint

   Recall the primary purpose of an amplifier.

5. 5.

   Given a common source amplifier with varying load capacitance values (50 pF, 100 pF, 150 pF), derive the upper cutoff frequency for each configuration.

   Hint

   Use different capacitance values in your calculations.

6. 6.

   Analyze how changing the biasing resistors in your common source amplifier affects the operating point and gain. Include calculations.

   Hint

   Reevaluate your circuit diagram with new values before calculating.
