Abstract :
Slow wave coplanar strips are fundamental elements in millimeter wave application. Based on four port scattering parameters, an equivalent lumped model is presented recovering the frequency independent parameters up to 110 GHz. The model parameters are generated based on two independent modes that propagate in two uniformly coupled propagating systems. All the coupling effects are considered. And no further fitting or optimization is required. The extracted SPICE-compatible model is validated by 65nm CMOS technology slow wave coplanar strips. We compare four port S-parameters. A very close agreement is obtained. The model is useful for various design applications.
