在分析Σ-Δ模数转换器原理的基础上,探讨了抽取数字滤波器的高效实现结构,通过MATLAB建模仿真设计了过采样Σ-ΔA/D转换器。采用多级联结构,降低计算复杂性,减少数字处理量,并有效地减小了硬件的功耗。
Abstract:Based on the analysis of the principle of Σ-ΔA/D converter,the extraction of high-performance digital filter structure is discussed.An oversampling Σ-ΔA/D converter is designed through the MATLAB modeling and simulation.Multi-cascade structure can reduce the complexity of calculation and the quantity of processing capacity, and also can reduce the hardware complexity and power consumption effectively.
