Hey Achim thanks for the reply! I'm actually just trying to design a circuit for 0-3.3V sensors so I don't really need a negative Vs- thats why I just set it to ground. The issue in my lab is that my signal generator outputs Vpp signals so they go negative. I just thought it would output the positive half then like it does at low frequencies. Do you think the response would be correct if I put a negative 3.3V rail in there? I wont' ever have anything to produce a negative voltage other than my signal generator i'm testing with. My A/D would get mad if I did have a negative voltage though I think.
What if I passed my signal generator output through a diode so I only got the positive half of the sine wave? Should I expect full bandwidth when passing only the positive portion through? That would actually be very easy for me to lab test.
