Question 1.
What is the formula for calculating voltage gain in a common source amplifier?
Show hintHide hint
Think about the parameters involved in amplifier gain.
Question 2.
What does the upper cutoff frequency indicate?
Show hintHide hint
Consider what happens to signals at very high frequencies.
3Question 3.
What is the voltage gain formula for a common source amplifier?
- Av = gm * RD
- Av = RD / gm
- Av = gm + RD
Show hintHide hint
Think again about how gain is derived.
4Question 4.
True or False: Cascading stages in amplifiers decreases overall bandwidth.
- True
- False
Show hintHide hint
Consider the purpose of combining amplifier stages.
Question 5.
Design a cascading amplifier circuit with a common source and a common drain stage. Given load capacitance of 50 pF, calculate the expected upper cutoff frequency if RD is 2 kΩ.
Show hintHide hint
You can change the values and test different configurations for better insight.
Question 6.
If the output of the common source amplifier is observed to have a gain of 8 instead of the calculated 6, discuss the potential reasons for this discrepancy.
Show hintHide hint
You might want to think about all the factors involved in amplifier performance.
