Implementation of Non-linear Circuit Models under the Tlm
نویسنده
چکیده
On the Printed Circuit Boards (PCBs), the interconnection geometry influences the ElectroMagnetic Compatibility (EMC) and the Signal Integrity (SI). The impact increases when circuits with a non-linear behavior are connected at their terminations. An accurate EMC analysis requires an electromagnetic solver including the model of those non-linear components. The insertion is made via lumped elements within the mesh of the TLM code. This work follows the macromodel hybridization with the finite-difference time-domain (FDTD) method [1] example. The paper is based on three parts. Sections II and III respectively recall the Mpilog software basis and TLM formulation used in Minisolve code. Section IV presents numerical and measurement results.
