摘要
为了充分发挥Σ Δ过抽样转换器的能力以获得最佳的系统性能 ,文章在分析直流电压、时钟抖动及电源的杂波等诸多因素对其影响的基础上 ,提出了适于Σ Δ过抽样转换器工作的最佳条件 ,对Σ
In order to fully utilize Σ Δ oversampling converter to acquire system optimal performance,the optimum conditions suitable for Σ Δ oversampling converter operation are proposed on the basis of analyzing the influence of direct voltage,clock vibrating and power noise wave etc. on the converter.The optimum conditions have a certain guide significance to system design,making and debugging.
