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.
