| 摘要 |
The invention relates to a method of linearization of the transfer characteristic of an analog-digital converter. The method is applicable to an analog-digital converter (1) with double integration, having a network connected to the reference inputs, said network comprising a capacitor (9) in parallel to a resistor (10), the voltage supply of the analog-digital converter (1) being performed by means of an analog switch (15) from a reference source (12). According to the invention, the method consists in closing the analog switch (15) during the measuring voltage integration and in opening the same during the reference voltage integration.
