Abstract: According to some examples, systems and methods are provided for voltage sampling using one or more analog-to-digital converters (ADCs) to sense divided portions of a sampled voltage (e.g., of an output signal), using the one or more analog-to-digital converters to provide a plurality of digital values representative of those divided portions, and combining the plurality of digital values to produce a total digital value representative of the sampled voltage. Such systems and methods can achieve a high resolution for the total digital value while permitting use of ADCs that have a resolution lower than would otherwise be required to achieve the high resolution.
