Abstract
The phase relation of clock signals to be applied to an interleave type analog-to-digital conversion apparatus having N analog-to-digital converters is calibrated by applying a repetitive reference signal to the N analog-to-digital converters. The digital values from the N analog-to-digital converters are selected at corresponding sampling points of successive cycles of the reference signal. The clock phase relation is adjusted such that the selected digital values are made substantially equal to each other.
