  • Process for the D/A conversion of signed binary codes of a Bi-polar, time-varying signal and a digital-to-analog converter employing this process
    Patent number: 5389928
    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.
