Question 1.
What does transconductance represent?
Show hintHide hint
Think about how current relates to voltage.
Question 2.
What is the ideal input and output resistance for avoiding loading effects?
Show hintHide hint
Imagine what would keep signals unaffected.
3Question 3.
What is the purpose of transconductance in feedback systems?
- To convert current to voltage
- To convert voltage to current
- To mix signals
Show hintHide hint
Consider the direction of signal transformation.
4Question 4.
True or False: High input resistance is desirable for avoiding loading effects.
- True
- False
Show hintHide hint
Think about how a weak signal can be reinforced.
Question 5.
Given a voltage input of 5V and a transconductance of 2 mA/V, calculate the resulting current output, ensuring to discuss the implications of loading effects if the output conductance is not zero.
Show hintHide hint
How does changing the input voltage affect the final current output?
Question 6.
Design a hypothetical transconductance system where input voltage varies. How would you maintain stability if the loop gain approaches unity?
Show hintHide hint
Which parameters are critical to monitor for stabilization?
