Abstract: Calibrating of A/D converters is carried out by obtaining adjustable reference voltages which are used in A/D conversion, comparing a first divided reference voltage of a full range voltage Vref, with a second divided reference voltage of Vref using analog to digital converters that are used in the A/D conversion; and adjusting at least one of said reference voltages to obtain a set ratio between said multiple ones of said reference voltages. The compared values can include a divided version of Vref, e.g., 3/8 Vref.

Abstract translation: 通过获得用于A / D转换的可调参考电压，将全范围电压Vref的第一划分参考电压与使用模数转换器的第二分频参考电压Vref进行比较来进行校准A / D转换器， 用于A / D转换; 以及调整所述参考电压中的至少一个以获得所述多个参考电压之间的设定比率。 比较值可以包括Vref的分割版本，例如3 / 8Vref。
