摘要： A system and method are provided allowing for successive approximation analog to digital conversion. A first differential voltage is sampled and held during a first cycle. The first differential voltage is converted to a differential current. A second differential voltage is generated based on the differential current flowing through parallel-coupled respective first and second variable resistances. First and second portions of the second differential voltage are compared to produce a comparison result therefrom. Successive approximation is used to generate a signal based on the comparison result, the signal being an output signal and being used to control resistances of respective ones of the first and second variable resistances during subsequent cycles.
