摘要：【中文】本发明属于模数转换技术领域，具体涉及一种模拟信号温度补偿方法。首先给定固定输入值进行变温测试，建立温度模型，得到输入值相对温度变化曲线，确定标定温度点后对每一个标定温度点下多组输入、输出数据，利用这些数据进行线性拟合，得到每一个标定温度点下的拟合公式，利用每个温度点下k值和温度值进行最小二乘拟合得到最终系数值，同时将每个标定温度点下b值的均值最为b的最终值。该方法相比传统的温度补偿方法具有原理清晰、操作简单等优点，可以大大提高标定效率。 【EN】The invention belongs to the technical field of analog-to-digital conversion, and particularly relates to an analog signal temperature compensation method.
