The Effects of Signal Trace´s Termination on Ground Bounce and Common-Mode Radiation

Based on the method of moments, the ground bounce on any arbitrary printed circuit structure as well as the common-mode current on any conductor that attached to the printed circuit structure is predicted. The method of moments is applied to obtain the impedance matrix, which can be used to determine the unknown current vector and the inductance matrix. With the inductance matrix and current vector, the potential difference between any two adjacent nodes is predicted. The effects of the signal trace´s termination on ground bounce and common-mode radiation are discussed through numerical results.
