Question 1.
What is the voltage gain for a common source amplifier where g = 2 mA/V and R = 3 kΩ?
Show hintHide hint
Use the formula A = g * R.
Question 2.
Define the term 'transconductance'.
Show hintHide hint
Think about how it measures signal amplification.
3Question 3.
What is the voltage gain if transconductance is 2 mA/V and output resistance is 3 kΩ?
- 2
- 4
- 6
Show hintHide hint
Use the formula A = g * R.
4Question 4.
True or False: The common source amplifier increases output voltage.
- True
- False
Show hintHide hint
Recall the primary purpose of an amplifier.
Question 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.
Show hintHide hint
Use different capacitance values in your calculations.
Question 6.
Analyze how changing the biasing resistors in your common source amplifier affects the operating point and gain. Include calculations.
Show hintHide hint
Reevaluate your circuit diagram with new values before calculating.
