D/A转换器非线性误差的一种自动修正方法

An Automatic Method to Correct the Linearity Error of D/A Convertor

本文简要地讨论了D/A 转换器的误差,利用线性回归的方法对D/A 转换器的非线性误差进行直线拟合,然后对回归系数采用硬件进行修正,以使D/A转换器的误差达到最小值.

The errors of D/A convertor are discusedin this paper.The best straight line curve canbe get using linear regression,A hardwarecircuit is introduced to correct the regressioncoefficient in order to minimize the D/Aconvertor error.
