Abstract
An analog-to-digital converter (ADC) system configured to receive a first and a second analog quantity and to provide a plurality of numerical parameters representative of the first and second analog quantities. The ADC system includes a first, a second, and a third ADC circuit, and a digital interface circuit. The first ADC circuit is configured to provide a first code representative of the first analog quantity and to provide a first analog residue quantity representative of the first analog quantity with respect to the first code. The second ADC circuit is configured to provide a second code representative of the second analog quantity and to provide a second analog residue quantity representative of the second analog quantity with respect to the second code. The third ADC circuit is configured to receive the first and second analog residue quantities, and to provide a third digital code representative of a difference of the first and second analog residue quantities. The digital interface circuit is configured to receive the first, second, and third codes, and to provide the plurality of numerical parameters representative of the first and second analog quantities.
