After a brief description of Folding ADCs, also compared with Two-Steps ADCs, the principle function of an interpolative structures for these converters has been analyzed. It has been underlying as this structure improves the performances of the whole ADC. Some considerations allow to quantify the best design choices. A simulation of the converter has been also realized by PSPICE.
