CPC classification number: G06F1/10

Abstract: An apparatus and method for timing skew calibration. For example, the apparatus may include an analog-to-digital conversion circuit configured to sample an input signal based on a clock signal and convert the sampled input signal into a digital code, a skew detection circuit configured to calculate a first sum of standard deviations for respective levels of the digital code, compare the first sum of the standard deviations with a previously calculated second sum of standard deviations, and select a smaller value from among the first sum and the second sum, and a compensation circuit configured to compensate for a skew of the clock signal based on the selected one of the first sum and the second sum.
