Methods and systems for calibration of a delay locked loop |
摘要 |
A method for calibrating a delay locked loop (“DLL”) having a plurality of delay segments, comprises: determining segment delay values for the delay segments; calculating a full-cycle delay value for an input signal to the DLL; adjusting one or more of the segment delay values as a function of the full-cycle delay value to generate one or more adjusted delay values; and calculating weights for the delay segments as a function of the segment delay values, the full-cycle delay, and the one or more adjusted delay values, wherein the weights are used to calibrate the DLL. |
