Web动态元素匹配(Dynamic Element Matching)通过随机地选择输出的电流源组合，将与输入信号有关的谐波能量转化为与输入信号无关的白噪声，因而可以在有较大的失配存在的情 … WebElement matching errors are inevitable due to inherent process variations. Although special layout techniques, special processes, and/or laser trimming can be used to reduce matching errors, these methods lead to significant cost increases. The dynamic element matching technique accepts matching errors as inevitable and dynamically
