在电路板的设计中采用光电耦合器件、铁氧体磁珠、旁路电容滤波等方式减小了噪声。

At last of design, use optocoupler device, ferrite beads and bypass capacitor to reduce system noise.

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。

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

由于逆变器电源对输出接地电容的限制，对严重的共模电磁干扰难以用大容量的共模滤波器抑制共模噪声。

With the limitation to the ground capacitance by inverter, it is difficult to suppress the severe common-mode noise by large CM filter.
