Numerical and experimental investigation of noise coupling perturbed by ESD currents on printed circuit boards

This work demonstrates an experimental setup with good repeatability for measuring the ESD-induced noise on high-speed PCB. The effect of the test system impedance and coaxial cables on the measurement of the discharge behavior is also theoretically and experimentally studied. The corresponding FDTD numerical method based on a novel ESD hybrid source model is proposed to predict the noise coupling phenomena in the high-speed printed circuits. The agreement between the numerical prediction and measurement results is good.
