Abstract :
The diffusion process in p-n junction diodes is modeled using the matrix rational approximation. The diffusion process is governed by the carrier continuity equation which is equivalent to an RCG transmission line. The matrix rational approximation here is used to provide a lumped network model of the RCG transmission line preserving the passivity. In an example, comparable accuracy with mixed-level circuit and device simulation and superior efficiency to different passive models are observed.
