1. An analog-to-digital converter, comprising:

  • a sample and hold tree comprising a first level and at least one additional level, each level comprising one or more sample and hold circuits operable to sample an input voltage and produce a corresponding output voltage, wherein the input voltage sampled by the one or more sample and hold circuits in each additional level comprises the output voltage from the one or more sample and hold circuits in a preceding level;

    a plurality of comparators, each comparator operable to compare the output voltage from one of the sample and hold circuits with one of a plurality of reference voltages; and

    a state machine operable to receive outputs from the comparators and generate a digital output value.
