Question 1.
What is output impedance?
Show hintHide hint
Consider how it affects the load connected to it.
Question 2.
Define transconductance.
Show hintHide hint
Look for a relationship with inputs and outputs.
3Question 3.
What is the formula for output impedance?
- R = V/I
- Output Impedance = 1/gₘ
- Z = V/I
Show hintHide hint
Look for the formula that includes gₘ.
4Question 4.
True or False: Higher transconductance leads to lower output impedance.
- True
- False
Show hintHide hint
Think about the relationship between these two values.
Question 5.
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.
Show hintHide hint
Use the output impedance formula to derive gₘ.
Question 6.
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?
Show hintHide hint
Think about how RC time constant relates to frequency.
