摘要
A method for calibrating a phase nonlinearity of a digital-to-time converter is provided. The method includes generating, based on a control word, a reference signal using a phase-locked loop. A frequency of the reference signal is equal to a frequency of an output signal of the digital-to-time converter. Further, the method includes measuring a temporal order of a transition of the output signal from a first signal level to a second signal level, and a transition of the reference signal from the first signal level to the second signal level. The method additionally includes adjusting a first entry of a look-up table based on the measured temporal order.
