摘要: 電流脈衝雜訊(Simultaneous Switching Noise,簡稱SSN) 是目前 與將來線路設計的瓶頸所在。由於電流密度隨著積體 化程度的增加 和操作頻率的增快而迅速增加,電流脈衝雜訊 的嚴重性與日遽增。 為了在設計電路時能夠預測電流脈衝雜 訊的影響,並且找到需要補 償雜訊傷害的位置,電流脈衝雜 訊模型的建立是必要的。因為傳輸 線模型(Transmission Line Model)的簡易和隨頻率變化的特性 ,使得傳輸線模型 在電流脈衝雜訊的建立非常有用。在本篇論文 中,我們用傳 輸線模型來預測電流脈衝雜訊的行為並用實驗結果驗 證之。 Abstract Simultaneous Switching Noise(SSN) is the bottleneck of the recent and future circuit design technology as the current density increasing. In order to predict the effect of SSN and find out the critical point, the use of transmission line model is presented. The simplicity and high frequency performance make this model useful. The behavior of SSN is studied by simulating and experimenting with the transmission line model. According to the distributed phenomenon of supply line, the double metal line technology is proposed. The influence of SSN is reduced by the combination of on-chip capacitor and double metal line. Some design rules are concluded for the circuit designer.
