摘要：
An analog-to-digital converter (ADC) includes a first operator configured to subtract an analog value from an analog signal; an amplifier configured to amplify an output of the first selector; a filter configured to filter an output of the amplifier; a quantizer configured to generate a digital bit stream from an output of the filter; and a digital-to-analog converter (DAC) configured to output the analog value according to the digital bit stream.
