对时频域混合方法加以改进用于分析电源分配网络同步开关噪声.引入修正Gram-Schmidt正交化方法实现矩阵的正交三角分解
以解决有理函数逼近构建时域宏模型中存在的病态条件数问题;同时提出一种结构简单的等效电路模型用于HSPICE电路仿真.计算实例验证了该方法的有效性.
The hybrid time-frequency method was modified to analyze the simultaneous switching noise in power distribution network.The matrix was decomposed in QR form using modified Gram-Schmidt orthogonal method to solve the ill-conditioned problem in macromodel construction in the time domain using rational function approximation.Meanwhile
a simple equivalent circuit model was presented for circuit simulation in HSPICE.Finally a specific numerical simulation study demonstrates the validity of the method.
