ABSTRACT:
An analog to digital converter having improved differential non-linearity is provided. The converter has a memory which is used to look up the actual weight or a weight error corresponding to the bits that have been kept as part of the SAR process to form an output correction value A part of this, for example a residue (the part following the decimal point in a decimal representation) is used to drive a correction DAC which causes a correction to be applied to the trial value presented to a comparator used by the ADC.
