摘要

Delta-Sigma调制器的并行设计概念，为工业应用中的高度动态位置控制优化了分辨率和带宽。该思想在印刷电路板上实现，并通过综合测量装置进行了测试。在固定频率下，有效比特数增加2.5比特。对于恒定分辨率，设计方法允许更小的滤波器长度和减少25%的延迟。

Parallel Delta-Sigma ADC modulation for performance increase of position sensors in industrial applications

A parallel design concept of Delta-Sigma modulators that optimizes the resolution and the bandwidth for a highly dynamic position control in industrial applications. The idea is realized on a printed circuit board and tested by using a comprehensive measurement setup. The effective number of bits is increased by 2.5 bits at a fixed frequency. For a constant resolution, the design approach allows smaller filter lengths and a decrease of the delay by 25%.
