Question 1
What is the ideal gain equation for 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 role of R_f and R_{in}!
Question 2
True or False: The output of an inverting amplifier is in-phase with the input.
- True
- False
π‘ Hint: Think about the impact of the negative sign in the gain.
