Question 1
What is the formula for output impedance?
- R = V/I
- Output Impedance = 1/gₘ
- Z = V/I
💡 Hint: Look for the formula that includes gₘ.
Question 2
True or False: Higher transconductance leads to lower output impedance.
- True
- False
💡 Hint: Think about the relationship between these two values.

Challenge Problems
Push your limits with challenges.
Question 1
Design a common drain circuit that can handle an input signal of up to 1V and requires an output impedance of 200Ω. Calculate the necessary transconductance.
💡 Hint: Use the output impedance formula to derive gₘ.
Question 2
Determine the impact on the cutoff frequency if the load capacitance of a common collector circuit is increased by 50%. What factors play a role in this?
💡 Hint: Think about how RC time constant relates to frequency.
