Abstract
An analog to digital conversion apparatus that includes an analog to digital converter (ADC), a linearity calculating module and a calibration module is provided. The ADC includes a capacitor array, a comparator and a control circuit. The capacitor array receives an input signal to perform a capacitor-switching to generate a capacitor array output signal. The comparator compares the capacitor array output signal and a comparing signal to generate a digital code output result. The control circuit controls the capacitor-switching according to the digital code output result. The linearity calculating module generates a linearity related parameter according to the digital code output result. The calibration module generates a weighting parameter according to the linearity related parameter when the linearity related parameter is not within a predetermined range to adjust the digital code output result based on the weighting parameter to generate an adjusted digital code output result.
