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