ABSTRACT:
An analog to digital converter which includes a resistive network for generating a number of first reference voltages related to each other by a first linear relationship and a number of second reference voltages related to each other by a second linear relationship, where the first linear relationship is different from the second linear relationship. Also included are first comparators which compare an analog signal to each one of the first reference voltages to produce specified first comparator signals where a respective comparator of the first comparators is provided for each of the first reference voltages. Second comparators are provided to compare the analog signal to each of the second reference voltages to produce second comparator signals where a respective comparator of the second comparators is provided for each one of the second reference voltages. Also included is an encoder to directly convert the first comparator signals and the second comparator signals to a linear digital encoded signal having respecting different quantization resolutions in different parts of its range.
