Question 1
What is the formula for the gain of an inverting amplifier?
- A_v = R_f/R_{in}
- A_v = -R_f/R_{in}
- A_v = R_{in}/R_f
π‘ Hint: Remember the negative sign indicates inversion.
Question 2
True or False: The output of an inverting amplifier is in the same phase as the input.
- True
- False
π‘ Hint: Think about the name 'inverting amplifier'.

Challenge Problems
Push your limits with challenges.
Question 1
An engineer designs an inverting amplifier with a feedback resistor of 200kΞ© and input resistor of 50kΞ©. If the input voltage is 2V, what is the output voltage?
π‘ Hint: Calculate gain first then use it to find the output.
Question 2
If you want to design an inverting amplifier to invert a 5V input signal and output should be 15V, what gain would you need, and what should be the resistor values if R_{in} is 10kΞ©?
π‘ Hint: First derive the gain then use it to find R_f.
