Claim 0:
1. A data acquisition system, comprising:
a signal transmission line comprising a plurality of first signal delay units connected in series, an output end of each of the first signal delay units forming an acquisition end;
a plurality of acquisition units each corresponding to a respective one of the first signal delay units,
wherein in each pair of a corresponding acquisition unit and a first signal delay unit, the acquisition unit is connected to the acquisition end of the first signal delay unit, to collect signals at the acquisition end;

a clock unit connected to each of the acquisition units, the clock unit comprising a first inversion unit and a plurality of second signal delay units,
wherein the first inversion unit and the plurality of second signal delay units are connected in series, the second signal delay unit are structurally the same as the first signal delay unit, and the clock unit is configured to generate a control signal for controlling a time for signal acquisition of the acquisition unit;

a comparison unit connected to the clock unit, the comparison unit being configured to compare a period of the control signal with a period of a standard signal, and to generate an adjustment signal according to a result of the comparison; and
an adjustment unit connected to the comparison unit, the adjustment unit being configured to adjust a supply voltage for the signal transmission line and the clock unit based on the adjustment signal, such that a ratio of the period of the control signal to the period of the standard signal is within a predetermined threshold range.
