Abstract
A method for evaluating capacitor weighting of an analog-to-digital (ADC) is provided. An equivalent weighting value of each composed capacitor in each sub-capacitor-array may be obtained by adding the switch device to the ADC which enables each sub-capacitor-array in a digital-to-analog (DAC) to be measured by each other. The ADC can calculate and then obtain a correct digital output by using the calibrated equivalent weighting and successive approximation result of each input signal.
