Transient simulation of lossy coupled transmission lines

The authors present a new approach for transient simulation of lossy coupled transmission lines terminated in arbitrary nonlinear elements. The approach is based on convolution simulation. By making use of the Pade approximation of the modal functions, the impulse responses of the multiconductor system are determined. A recursive convolution formulations is derived for the impulse responses. The stepwise equivalent conductance integration technique is employed: therefore, no Newton-Raphson iteration is needed for the implicit integration of the circuit. The approach can handle general coupling situations
