Ground Bounce Noise not only transmits in its own power/ground plane, but also couples to neighboring power/ground plane. Moreover, the thesis presented electromagnetic radiation effect by noise coupling problem which uses the double summation Z method to discuss this noise problem. In an arbitrary shape PCB, this thesis uses the segregation Matrix method to discuss the noise problem. However, it may compute those effects for a long time. Therefore, this thesis derives a fast algorithm that modifies double summation to single summation. It is common practice to suppress resonant mode by decoupling capacitors. The decoupling capacitors make the resonance frequency higher than the operation frequency and it can suppress the noise to make the circuit component work successfully. Furthermore, Particle swarm optimization is performed to find the optimal positions of decoupling capacitors. This particle swarm optimization also reduces the capacitor numbers to achieve the optimum result. The main achievement of this thesis is to develop a powerful model expansion method for solving arbitrary shape PCB, and determine the locations of decoupling capacitors. Any unwanted resonant frequency can be suppressed by decoupling capacitors specified by this method. Simulation and Measurement results prove that the present method is very useful and practical in the issue of power integrity (PI). Ding-Bing Lin 林丁丙 2011 學位論文 ; thesis 54 zh-TW |

碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 99 === This thesis discusses the Ground Bounce Noise in today’s high-integrative and high-complexity circuit designs. Ground Bounce Noise not only transmits in its own power/ground plane, but also couples to neighboring power/ground plane. Moreover, the thesis presented electromagnetic radiation effect by noise coupling problem which uses the double summation Z method to discuss this noise problem. In an arbitrary shape PCB, this thesis uses the segregation Matrix method to discuss the noise problem. However, it may compute those effects for a long time. Therefore, this thesis derives a fast algorithm that modifies double summation to single summation.
It is common practice to suppress resonant mode by decoupling capacitors. The decoupling capacitors make the resonance frequency higher than the operation frequency and it can suppress the noise to make the circuit component work successfully. Furthermore, Particle swarm optimization is performed to find the optimal positions of decoupling capacitors. This particle swarm optimization also reduces the capacitor numbers to achieve the optimum result. The main achievement of this thesis is to develop a powerful model expansion method for solving arbitrary shape PCB, and determine the locations of decoupling capacitors. Any unwanted resonant frequency can be suppressed by decoupling capacitors specified by this method.
