ABSTRACT:
A system for randomizing aperture delay in a time interleaved ADC system that includes a plurality of selection switch stages corresponding to each of the ADCs in the system and a second selection switch stage coupled to a voltage source. A plurality of conductors extend between the second selection switch stage and each of the selection switch stages, in excess of the number of ADCs in the system. For each of N ADCs in the system, the selection switch stages and the second selection switch stage support at least N+1 selectable conductive paths extending from each of the sampling capacitors of the ADCs to the voltage source. Random selection of the N+1 paths can randomize aperture delay.
