Abstract
An analog to digital converter, comprising a first converter adapted to perform a first, more significant, part of a conversion as a successive approximation conversion, a pipeline conversion or a flash conversion to generate a first conversion result and a residue. The ADC also comprising a second converter adapted to perform a second, least significant, part of the conversion as a sigma-delta conversion by sampling the residue to generate a second conversion result, and a processor adapted to combine the first conversion result and the second conversion result to generate a final conversion result.
