Abstract
Various methods, systems and apparatuses having an integrated circuit that contains a calibration circuit having a series of delay elements to receive a reference signal. The reference signal establishes a standard unit of time. The calibration circuit also generates one or more calibrated delay signals derived from the reference signal. The one or more calibrated delay signals are precise to a known fraction of the standard unit of time.
