Abstract
A method and system for converting a plurality of input signals being indicative of a signal to be converted to a digital output including: setting a plurality of codes each being indicative of a corresponding reference level; and, for each one of the codes, converting the one code to a first analog signal, and summing the first analog signal with a first of the input signals to provide a first summed signal; complementing the one code to provide a complemented code, converting the complemented code to a second analog signal; summing the second analog signal with a second of the input signals to provide a second summed signal corresponding to the first summed signal. The corresponding first and second summed signals are compared to provide a comparison signal. At least a portion of the digital output is set according to the comparison signal.
