AMC3306M05: Delay from input signal to output signal of AMC3306M05.

Part Number: AMC3306M05

I would like to know the delay from the input signal to the output signal of AMC3306M05.

In the Delta Sigma Modulator Filter Calculator, the delay of control loop filter module is given by "Filter Setting Time". But I don't know how much time it takes for the signal to go from the input to the output of the Delta Sigma Modulator.

  • 您好,

    Delta Sigma Modulator Filter计算器中,黄色表格是输入参数,绿色表格是输出结果,输入Modulator frequency 和 OSR 可以在对应的表格内得到Filter Setting Time和 ENOB参数:

  • 您好,

    是否在delta-sigma modulator环节就没有时间延迟?

  • Δ-Σ 调制器它的作用是将模拟波形转换为Bit流。可以将此功能的实现分为两步。第一步是使用开关和电容器的网络组成“采样保持”电路,对输入信号进行采样。第二步是转换采样电压。可以将采样保持电路想象成具有极高带宽的电阻电容 (RC) 网络。在采样发生时,输入电压必须达到稳定状态,因此这里肯定存在延迟,但采样电路必须快速充电,以满足采样时序要求。

    Δ-Σ 调制器的架构都是严格保守的行业秘密,但一般来说,采样保持电路和位流输出之间的任何延迟将不会大于调制器的几个时钟周期。调制器的几个时钟周期的延迟显著小于数字抽取滤波器的群延迟。
