Greetings,
I found an interesting circuit in the article found in figure 1d).

I tried to duplicate it with circuit simulator and with real components.
Instead of MAX4684 chip, I used MAXDG307ACJ+-ND digikey.
Instead of capacitor 33nF I used 47nF.
On PC simulator I used DG303 and the circuit gives output as expected.
However when I used real components, I am not getting two peaks (one positive and one negative)
I have checked the chip and it works fine. It does not work when I use resistor and capacitor. My output is the same as input of signal which is 50% duty square waves at about 2 Hz. Am I missing something here? I have checked the circuit and it is layed out as in the drawing.
