Kind Code:
A1
Abstract:
A method and device for improving the output accuracy of a digital-to-analogue converter. The method comprises: calculating output errors of a digital-to-analogue converter according to the output accuracy and input errors of the digital-to-analogue converter (S11); acquiring at least one of the output errors, and comparing same with a pre-set threshold; and adjusting an integer input value of the digital-to-analogue converter according to a comparison result (S12).
