With this shield in place, the noise current generated by the electrostatic voltage source and the coupling capacitance flows through the shield to ground rather than through the signal conductors.

有了这种屏蔽，由静电电压源和耦合电容产生的噪声电流就经过屏蔽流到地，而不再流过信号线。

Noise can seriously affect sensitive current measurements. This section discusses how source resistance and source capacitance affect noise performance.

噪声能够严重地影响灵敏的电流测量工作。本节讨论源电阻和源电容如何影响噪声的性能。

In addition, LC noise filter is added in the tail current source to lower phase noise further more.

另外，在尾电流源处加入电感电容滤波，进一步降低相位噪声。
