This article presents a new algorithm for time-domain circuit simulation based on numerical inversion of Laplace transform (NILT). The proposed method, labeled NILT $n$ , shows that for the same computational cost of the conventional NILT, referred to as NILT0, the approximation error is reduced by a significant factor, permitting time-marching with much larger time steps and, consequently, saving significant computational cost per time step. Numerical experiments are presented to demonstrate the efficiency and accuracy of the proposed approach.

基于拉普拉斯变换修正数值反演的快速稳定时域仿真


本文提出了一种基于拉普拉斯变换数值反演（NILT）的时域电路仿真新算法。所提出的方法（标记为 NILT $n$ ）表明，对于与传统 NILT（称为 NILT0）相同的计算成本，近似误差显着降低，允许使用更大的时间步长进行时间推进，因此，每个时间步节省大量计算成本。数值实验证明了所提出方法的效率和准确性。
