ABSTRACT:
Analog to digital conversion of signals at rates higher than can be accomplished by a monolithic flash analog to digital converter is achieved using multiple flash analog to digital converters operated in a parallel architecture. Sample timing of the multiple converters is skewed by selecting subfrequencies of a control clock or different phases of a control clock as the source for the sample control signal. The multiple flash converter outputs are then digitally recombined to produce a single output identical to a flash converter operating at a higher speed than could be obtained for a given set of circuit parameters.
