Имплементация элементов с лапласовскими передаточными функциями в программу схемотехнического моделирования
The paper presents an approach to the implementation of multiport linear dynamical blocks in a
circuit simulator. Block characteristics are supposed to be presented in the form of rational transfer functions. The
approach is based on the state space method, which allows avoiding problems of numerical convolution. The extension of the approach to the case of the exponential-rational form of transfer function is taken into account. The MNA formulation of Laplace element model is presented. The methodology providing construction of arbitrary multi-port Laplace elements on the base of developed set of simple Laplace elements is proposed. The approach was
implemented in SPICE3 circuit simulator. Examples are given in the paper.
