Power plane system of high-speed digital circuit for suppressing ground bounce noise |
摘要 |
The invention relates to a power plane system for suppressing ground bounce noise. The power plane system of the invention comprises a substrate, a power layer and a ground layer. The power layer comprises a plurality of metal units. There is a distance between two adjacent metal units. A plurality of bridges is used for connecting the metal units. The ground layer has a grounding metal plate. According to the invention, when the ground bounce noise occurs, the metal units can broaden the stop-band bandwidth. Therefore, the signals in the stop-band hardly are transmitted so as to suppress the ground bounce noise, and the high frequency ground bounce noise and the electromagnetic radiation can be suppressed efficiently. |
