Calibration of timing

摘要

A method for calibrating time interleaved samplers comprises applying (102) a calibration signal to a time-interleaved sampling device, wherein the signal is coherent with at least one sample clock on the device and is periodic and has a predetermined spectral content and frequency, sampling (104), by said time-interleaved sampling device, the calibration signal at a plurality of phases to form samples, averaging (106) the formed samples, and calculating (108) the phase error of each sample based on the average calibration signal sample.
