Hi Tacey
Thanks For the reply. I will update the location of 18 Ohm current limiting resistor.
I agree with you that 0 Ohm condition is valid. But for educational purpose can you pl. explain why is 0 Ohm condition valid.
Is it because it has a independent Current source?
Secondly, How is it related to the OutPut Impedance = 50Mohm as mentioned in the data ?
Pl. bear with me if i'm asking silly questions.!!!
Thanks
