Abstract
An analog-to-digital converter (ADC) device includes ADC circuitries, a calibration circuitry, and a skew adjusting circuitry. The ADC circuitries convert an input signal according to interleaved clock signals, in order to generate first quantized outputs. The calibration circuitry performs at least one calibration operation according to the first quantized outputs to generate second quantized outputs. The skew adjusting circuitry analyzes time difference information within even-numbered sampling periods of the clock signals, in order to generate adjustment signals. The adjustment signals are for reducing a clock skew in the ADC circuitries.
