Question 1.
What is trans-impedance?
Show hintHide hint
Think about the output signal relative to the input signal.
Question 2.
Define input resistance in the context of amplifiers.
Show hintHide hint
Consider what happens when a signal first enters an amplifier.
3Question 3.
What does trans-impedance represent in an amplifier?
- Output current to input voltage
- Output voltage to input current
- Input voltage to output voltage
Show hintHide hint
Recall the definition of trans-impedance.
4Question 4.
True or False: In a shunt-shunt configuration, we mix output voltage with input current.
- True
- False
Show hintHide hint
Consider how the configuration is set up.
Question 5.
Design an amplifier circuit with R values of your choice. Calculate the resulting input resistance and trans-conductance when utilizing a shunt feedback.
Show hintHide hint
Apply the feedback principles discussed in class.
Question 6.
Analyze the effects of changing the feedback resistance on circuit stability and performance. What happens if R is increased or decreased?
Show hintHide hint
Think about how resistance impacts feedback influence.
