Question 1.
What does the term open-loop gain refer to?
Show hintHide hint
Think about how much the output changes with small input changes.
Question 2.
Why is a high open-loop gain desired?
Show hintHide hint
Consider applications where signal clarity is key.
3Question 3.
What is the formula for open-loop gain in an op-amp?
Show hintHide hint
Remember to think about what each variable represents.
4Question 4.
True or False: The open-loop gain decreases when feedback is applied.
- True
- False
Show hintHide hint
Consider how feedback affects sound systems.
Question 5.
If an op-amp has an open-loop gain of 200,000 and we want the output voltage to be 10V, what voltage difference is required at the inputs?
Show hintHide hint
Use the formula to isolate the voltage difference.
Question 6.
Describe how an increase in the open-loop gain would affect the stability of an op-amp circuit.
Show hintHide hint
Think about how a tighter grip can affect balance in a see-saw.
