Patent abstract
A method for operating an N-bit SAR ADC as a greater than N-bit resolution SAR ADC includes the steps of taking a plurality of samples for each analog value being converted to a digital value by the SAR ADC. A portion of an LSB is added to all but one of the plurality of samples. The plurality of samples are then accumulated and output as a digital value. The digital value has a resolution greater than the N-bit resolution of the SAR ADC.
