My amps at the output were 0.25ma. I did not have any luck using the second op amp to boost my signal. How should this be connected? The circuit and output are below.

"configuration below" does not have values of the resistors. Telling us that you used "configuration below" tells us nothing.In my lm358 I tried hooking up my sine wave output from my 1st op-amp to my 2nd. (LM358 has 2 op-amps). I used the configuration below. NUTHIN! But when I used a non-inverting voltage follower circuit I got the same wave form. I did this to estimate that the 2nd op-amp had at least continuity. What needs to happen to make this amplify?
Yeah, this makes sense, the second op amp becomes low pass filter, and since the pass band is tiny, frequencies higher than pass band are blocked so output is whole lot of nothing.Well, whatever else may be wrong, the LM358 has almost no bandwidth at 1000x (!) gain...most op amps don't; this much gain would be set up as the product of several successive gain stages (also unconvinced you actually need this much gain...explain?)
Two things you can do:I got my second op-amp in my lm358 to amplify, but it's clipping my negative wave. Thoughts? (I know I'm a pain in the butt)
