Abstract: Disclosed herein is a filter device for suppressing ground bounce and electromagnetic interference. The filter device comprises a dielectric substrate, a signal transmission layer, a signal via, a plurality of ground vias, and first, second, and third metal layers. The signal transmission layer is located on the dielectric substrate, the vias and the first and second metal layers in the dielectric substrate, and the third metal layer underneath it. The first metal layer has a filter portion and a resonance portion. The ground vias connect the second and third metal layers and are disposed perpendicularly to them. The signal via, disposed in a via space defined by the ground vias, connects the first metal layer and the signal transmission layer. As a result, the resonance portion is able to reduce noise of a certain frequency band, the ground vias abate ground bounce, and electromagnetic interference is minimized.

Abstract: A circuit board includes a substrate, two signal lines, two ground lines and two ground vias. The substrate includes a signal layer, a ground layer and an insulation layer. The signal layer is spaced apart from the ground layer. The signal lines are disposed on the signal layer with a first distance between the signal lines. The two signal lines are symmetrical about a reference line. The ground lines are disposed on the signal layer with a second distance between the first signal line and the first ground line. The second ground lines are disposed on the signal layer with one of the ground lines including two line portions having different widths. One of the ground vias is located at a joint between the two line portions. The two ground vias are symmetrical about the reference line.
