Abstract
In one embodiment, an analog-to-digital converter (ADC) includes a comparator and a supply circuit. The comparator is configured to compare an input signal to a reference signal. The supply circuit is configured to supply the reference signal. The supply circuit is configured to provide different circuit configurations for supplying the reference signal during different stages of analog-to-digital conversion such that the reference signal is scaled in substantially a same manner during at least two of the stages.
