摘要
The invention concerns an analog-to-digital converter, comprising programmable circuits generating (1) an image electric current proportional to the sum of active voltage values forming a series of voltage levels in geometric progression and corresponding to electric voltage values for which the analog image of the bit weight corresponds to a bit of value 1 and first programmable corrector circuits (2) receiving the image electric current and generating a first corrected analog voltage, being the difference between the supply voltage and the weighted sum of the active values. A second corrector circuit (3) of said first voltage generates a second corrected analog voltage substantially equal in quantity and sign to the weighted sum electric voltage active values. Third corrector circuits (4) of the second voltage enable to apply a programmed gain, inversely equal to the weighting term, thereby enabling to generate the converted analog voltage. The invention is useful for producing integrated circuits.
