It is found that the exciting signal coupled through the distributed capacitor between the exciting resistor and the sensing resistor is the final source of CFD.
发现通过激励电阻与拾振电阻间的分布电容耦合的激励信号是同频干扰的最终来源。
If the signal source were direct connected instead of capacitor coupled, there would be a low resistance path from the.
如果信号源和电路不是用电容耦合而是直接相连，从基极到负电源线就会一个低阻通路，并且这将影响到电路偏置状态。
