Abstract
The process for the conversion of a digital code involves the construction of two positive unipolar voltages (Vo+, Vo-) ranging between the analog ground level (Vgnd) and an upper full scale level (Vref), and the shifting downward of the second one (Vo-) of these voltages by a quantity equal to its maximum range, so to obtain two unipolar voltages (Vo+, Vo-) and with an amplitude equal to the halved module of the final stage.
