本教程介绍了两种数字技术,它们都旨在提高delta-sigma数据转换器的精度。第一个自适应校正MASH ADC中的失配误差,而另一个采集并校正ADC中使用的内部多位DAC的非线性。
Two digital techniques are described in this tutorial, both aimed at improving the accuracy of delta-sigma data converters. The first one corrects adaptively for mismatch errors in a MASH ADC, while the other acquires and then corrects for the nonlinearity of the internal multibit DAC used in the ADC.
