METHOD AND APPARATUS FOR ANALOG-TO-DIGITAL CONVERTER

摘要

Aspects of the disclosure provide an analog-to-digital converter (ADC). The ADC includes a comparator module and a digital-to-analog converter (DAC). The comparator module is configured to compare a first voltage sampled from an analog signal and a second voltage output from the digital-to-analog converter (DAC), and output a pulse to indicate a result of the comparison. The DAC is configured to enable a switching unit corresponding to a digital bit to switch a state based on the pulse, and settle the second voltage.
