摘要： A method for trimming reference voltage circuitry includes defining a desired target reference voltage for a set of at least one die. At least two reference voltages are measured for at least two different trim settings associated with a given die of the at least one die. A modified target reference voltage is determined for the given die based on the at least two measured reference voltages. A trim setting associated with the reference voltage circuitry of the given die is set according to the modified target reference voltage so as to compensate for an offset voltage and substantially achieve the desired target reference voltage.
