Abstract
An analog to digital converter (ADC) device includes ADC circuitries, a calibration circuitry, and a skew adjustment circuitry. The ADC circuitries are configured to convert an input signal according to interleaved clock signals, in order to generate first quantization outputs. The calibration circuitry is configured to perform at least one calibration operation according to the first quantization outputs, in order to generate second quantization outputs. The skew adjustment circuitry is configured to determine maximum value signals, to which the second quantization outputs respectively correspond during a predetermined interval, and to average the maximum value signals to generate a reference signal, and to compare the reference signal with each of the maximum value signals to generate adjustment signals, in order to reduce a clock skew of the ADC circuitries.
