PCB上的串扰的产生机制，可以认为有三种：电感耦合，电容耦合还有共阻耦合(common-impedance coupling)。 电感/电容耦合 假设两条微带线，中心到中心的距离为d，如下图所示。 当信号沿着传输线传播时，微带线周围开始有电场线和磁场线。 但是，这些电场线和磁场 ...

The development of digital common-mode noise starts with digital circuit devices. Peak overshoot and undershoot currents from the devices conduct into the power and return planes to result in this ...
