Abstract
A method and a corresponding device for reducing inter-channel coupling in a circuit having a plurality of channels includes injecting a randomly determined amount of dither into a first channel of a circuit having a plurality of channels, and after injecting the dither, obtaining an output signal of a second channel in the plurality of channels. A correlation value indicating a degree of correlation between the injected dither and the output signal is determined, and an amount of charge applied to the second channel due to cross-coupling with the first channel is reduced. The amount of the reduction is calculated as a function of the correlation value.
