Hey everyone need to make a device to raise my signal voltage. My signal voltage varies between .2~.8v, I need to be able to add 0~.2 volt to this signal making it .2~1.0 volts total. So basically the user can adjustable to add extra 0volt to .2 volts. This is a very low current circuit, under 20ma. Also it should be isolated.
I'ma newbe so I have no clue how one would go about this besides adding a battery with .2volts in series with the signal voltage which i think would work but it would not be adjustable and i would need to change the battery...
Few ideas I've had:
Usa a small solar cell inline with the signal voltage and vary the amount of light the solar cell see to vary the raised voltage... But this seems like a super slow circuit and not sure if the original signal voltage of .2v~.8v would go though the solar cell in the first place...
Any other ideas?
