METHOD OF CALIBRATING AN ANALOG-TO-DIGITAL CONVERTER, AND A CALIBRATION EQUIPMENT |
摘要 |
A calibration equipment for calibrating an analog-to-digital converter, which calibration equipment comprises means for supplying control codes to the analog-to-digital converter, whereupon a digital value is obtained as the output of the converter, means for calculating a residual of the voltage sector to be calibrated as a difference of the second and the first digital value, means for calculating a correction term related to the voltage sector by adding the correction term of the adjacent calibrated voltage sector to the residual of the voltage sector and means for using the correction term in correcting the digital value obtained from the analog-to-digital converter when the analog-to-digital converter is used to convert a signal included in the voltage sector from an analog into a digital form.
