Just wondering if anyone could help me with this problem?
What is the minimum value of RL if |Io| must be less than 75 mA for |VIN| < 0.8 V?
R2 = 8.5 kΩ, R1 = 9.9 kΩ
For my attempt I used the formulas:
(Vo/Vi) = -(R2/R1)
Io = Vo/(RL || (R2+R1)
and got an answer of 9.16 ohm, but that was incorrect. (It should be 19.8 ohms)
