A multi-channel analog-to-digital converter system includes an array of sub-analog-to-digital converters wherein within the array of sub-analog-to-digital converters, there is at least one designated reference analog-to-digital converter. The analog-to-digital converter system also includes a non-sequential channel select circuit to control a selection of the analog-to-digital converters and the reference analog-to-digital converter to non-sequentially interleave the outputs of said analog-to-digital converters and said reference analog-to-digital converter. Each channel of the plurality of sub-analog-to-digital converters includes a timing skew estimation circuit. Each timing skew estimation circuit receives an output signal from the reference analog-to-digital converter and receives the output signal from the associated analog-to-digital converter. Each timing skew estimation circuit generates a timing signal to be used in shifting or adjusting the actual or apparent sample times for the appropriate analog-to-digital converter.
