Abstract
An analog-to-digital converter includes a sample and hold tree having a first level and at least one additional level. Each level includes one or more sample and hold circuits operable to sample an input voltage and produce a corresponding output voltage. The input voltage sampled by the one or more sample and hold circuits in each additional level represents the output voltage from the one or more sample and hold circuits in a preceding level. The analog-to-digital converter also includes a plurality of comparators. Each comparator is operable to compare the output voltage from one of the sample and hold circuits with one of a plurality of reference voltages. In addition, the analog-to-digital converter includes a state machine operable to receive outputs from the comparators and generate a digital output value.
