According to various embodiments, a system, an apparatus and a method are presented that relate to determining and correcting signal imbalances between output samples of an analog-to-digital (A-D) converter array (that may be implemented as part of a wideband ADC). A statistic module and correction module are associated with the A-D converter array. The statistic module is configured to receive digital samples from the plurality of A-D converters, and generate a statistical sample value for each A-D converter using a set of digital samples received therefrom. The correction module is configured to, for at least one of the plurality of A-D converters, determine an offset value by comparing the statistical sample value for the at least one of the plurality of A-D converters with a reference value, and apply the offset value to a digital sample from that at least one A-D converter to generate a corrected digital sample.
