ABSTRACT:
The present invention can provide an integral A-D converter of high frequency and of high accuracy and capable of reducing the influence of the integrating capacitor caused by the electric charge absorption property thereof because it compensates the measured data by substracting the compensating data from the measured data, the compensating data being the repeatedly A-D converted data of the ground voltage during the standardized initiating time of the integrating capacitor.
