摘要：

This paper describes the suppression of Ground Bounce Noise (GBN) or Simultaneous Switching Noise (SSN) in high Speed printed circuit board (PCB). The effectiveness of the slot length in the common ground / power plane in the-PCB for the coupling noise is simulated using Ansoft-HFSS (High Frequency Structure Simulator) package. The position of feed point between the two planes optimized was presented. A simple configuration was devised to reduce the coupling noise in the frequency range of interest. Better than -50 dB coupling is achieved using this optimized structure in the frequency band of 0.48 - 1.83GHz. The various stages of design optimization of the PCB is discussed for the new structure keeping in view of practical solution to achieve low coupling in the high speed PCB.
