摘　　要：本文提出一种基于快速小波配置法（FWCM）的非线性动态电路时域稳态模拟方法。该方法可以对电路瞬态响应过程用大步长（低阶小波）模拟，而对稳态响应过程用小步长（高阶小波）模拟，从而避免了为得到电路稳态响应而在瞬态响应时期花费大量的模拟时间。并且，该方法具有较低的计算复杂度。一些模拟结果证明，本文的方法是一种十分有效的方法。A new method based on FWCM (fast wavelet collocation method) for time domain steady state simulation of nonlinear dynamic circuit is proposed. Using this method, the simulation can be performed with large step (low order wavelet) for transient state response, and small step (high order wavelet) for steady state response so that the excessive computing time for transient state simulation can be saved. Furthermore, the computational complexity with the proposed method is greatly reduced. Some simulation results prove the efficiency of this method.
