method and apparatus for reducing inter-channel coupling in interleaved and multi-channel ADC

摘要

The method and corresponding apparatus for reducing inter-channel coupling in the circuit having a plurality of channels , and be introduced into the first channel circuit having a dither multiple channels of amount determined randomly dither after the introduction , including a to obtain an output signal of the second channel in a plurality of channels , a . Correlation value indicating the degree of correlation between the introduced dither the output signal is determined , the amount of charge applied to the second channel due to the cross-linking of the first channel is reduced . The amount of reduction is calculated as a function of the correlation value .
