Abstract
An apparatus comprises: a coarse voltage level comparator that generates a coarse voltage level comparison; a folder, a fine analog to digital (ADC) comparator coupled to an output of the folder, wherein an output of the fine ADC is cyclical; an up encoder coupled to an output of the fine ADC encoder, the up encoder configured to output a first value if the cyclical output of the fine ADC is in a defined downward transition; and a fold information generator coupled to an output of the up encoder, wherein the fold information generator is configured to generate a determination as to in which fold an analog voltage occurs.
