说明：  Delta-Sigma转换器是采用超采样的方法将模拟电压转换成数字量的1位转换器，它由1位ADC、１位DＡC与一个积分器组成，见图1。Delta-Sigma转换器的优点表现在低成本与高分辨率，适合用于现在的低电压半导体工业的生产
(Delta-Sigma converters are super-sampling method to convert the analog voltage of a digital converter, which consists of an ADC, 1 Wei DAC with an integrator component, shown in Figure 1. Delta-Sigma converter performance advantages of low-cost and high-resolution, suitable for use in the current production of low-voltage semiconductor industry)
