Accelerated Modal Network Synthesis for Arbitrary Interconnection Structures Through a Model-Order Reduction by a Static-Mode Extraction

An accelerated method for generating a broadband modal network model for 3D-interconnection structures is presented. By extracting the static modes from the system matrix, the order of the quasi-static eigenvalue problem to be solved can be significantly reduced. The influence of the static modes can be taken into account afterwards via the use of coupled port inductances, which can be determined via one simple network simulation. Thus, a modal multiport network model is derived with minimal computational effort, offering time domain simulations with arbitrary active/passive non-linear loads. The proposed method is validated by an example interconnection structure in the frequency and time domain.
