ABSTRACT:
An analogue to digital converter using several flash converter units to convert successively the increasingly lower orders of resolution, wherein the transition from a stage of lower magnitude of resolution to that stage of successively higher magnitude of resolution is obtained by physically isolating the resistor element of the resistor ladder of the first flash converter wherein the unresolved portion of the input voltage falls, and substituting a second flash converter comprising a resistor ladder of same total resistance as the resistor element it replaces but of higher resolution by one order of magnitude; then repeating the same with each successive flash converter.
