Abstract
A conditional correlated multiple sampling (CCMS) single slope (SS) analog-to-digital converter (ADC) is provided. The CCMS SS ADC includes a comparator, arranged to compare an analog signal with a ramp signal and generate a comparison result; and a CCMS control circuit, arranged to determine a swing of the ramp signal according to a magnitude of the analog signal. An image sensor system using the CCMS SS ADC and a method of CCMS SS analog-to-digital conversion are also disclosed.
