Question 1
What is the voltage gain formula in a common source amplifier?
- A_v = R_D / R_in
- A_v = g_m * R_D
- A_v = R_in * g_m
π‘ Hint: Focus on understanding the role of transconductance.
Question 2
True or False: Input resistance affects the signal strength that can be amplified.
- True
- False
π‘ Hint: Remember how resistance interacts with voltage and current.

Challenge Problems
Push your limits with challenges.
Question 1
Design a multi-stage amplifier that uses a common source followed by a common drain stage. Specify component values and justify your choices based on expected voltage gain and input resistance.
π‘ Hint: Consider the required specifications for voltage gain and input resistance. Analyze each stage's contribution.
Question 2
In a given circuit, if the input resistance is found to be 100 kΞ© and the desired conditions change causing it to increase by 50%, what is the new input resistance?
π‘ Hint: Simply calculate 50% of the current resistance and add it back.
