hello forum. i have a negative signal, that ranges from 0 to -0.9 volt, and i want to make possitive (1-1 ratio).
i know that the theory suggets, that i use a buffer inverting amplifier, but the problem is, i do not have a negative VCC in my circuit (or dont plan to anyway..)
but since i dont want the op-amp to generate any negative voltage, is it really neccecery to have a -VCC??
i am talking for a circuit like this :
