ABSTRACT:
A timing calibration system for an adjustable delay time of a delay module for an electronic circuit is provided. The system includes a control delay module including at least one calibration delay module, the control delay module having a second delay time. The system also includes a timing module associated with the control delay module, a comparison module associated with the timing module and an adjustment module for the delay module. The timing module measures the second delay time, the comparison module compares the second delay time with a desired delay time and produces a comparison result and the adjustment module calibrates the adjustable delay time utilizing the comparison result.
