They achieve these speeds by running a bank of comparators that operate in parallel, each for a defined voltage range.

WebbParallel flash converters use a bank of comparators that compare the input voltage to a set of reference voltages across a resistor network. The voltages start at a value equal to that for one-half the least-signifi-cant bit (LSB) and increase in equal voltage incre-ments equivalent to one LSB for each comparator.
