摘要: A method and apparatus for decreasing resonance in a printed circuit board (PCB) uses cuts in a ground plane to slow a signal passing through the ground plane. Cuts in the ground plane may be used alone or in conjunction with the lengthening of signal traces.

摘要: A method for decreasing resonance in a printed circuit board (PCB) uses cuts in a ground plane to slow a signal passing through the ground plane. Cuts in the ground plane may be used alone or in conjunction with the lengthening of signal traces. Slowing the signal passing through the ground plane enables a mismatch between the signal transit time of the ground plane and a signal oscillation period of the circuit board to be obtained. The mismatch results in decreased resonance.
