Abstract: An analog-to-digital converter (200) with a pipeline architecture for converting an analog input signal into a digital output signal with a predefined resolution is proposed. The converter includes a plurality of stages (105 3 -105 0 ) each one having means (110,115) for converting an analog local signal into a digital local signal with a local resolution lower than said resolution, means (120,125) for determining an analog residue indicative of a quantization error of the means for converting, and means (130) for amplifying the analog residue by an inter-stage gain corresponding to the local resolution to generate the analog local signal for a next stage, and further includes means (204) for combining the digital local signals of all the stages into the digital output signal weighting each digital local signal according to a digital weight depending on the corresponding inter-stage gain. In the converter of the invention, the means for combining includes, for at least one of the stages (105 3 ), means (205-240) for dynamically estimating a digital correction signal indicative of an analog error of the corresponding inter-stage gain, and means (230) for controlling the digital weight according to the digital correction signal.

Abstract: A test signal (TS) with given spectral characteristics is injected (201) at input to the quantizer stage (20) of the converter. The same test signal (TS) is subjected to cross-correlation (30) with a given signal (Y(z)) so as to generate (31) coefficients used for filtering (32) the quantization noise converted (27) into digital form. In this way, a compensation signal is obtained which is applied to the output signal of the quantizer stage (20) jointly with a first compensation signal obtained by applying, to the quantization noise converted into digital form, the same transfer function (28) of the converter. In this way a signal is obtained which, in addition to being used as the global output signal (Y(z)) of the converter, is also used for the aforesaid operation of cross-correlation with the test signal (TS).
