In this paper, a new formulation is provided to model the noise coupling between adjacent planes in a multilayer stackup. A model is developed to show that the planar coupling depends heavily on the wave impedance of each power plane. Also a rigorous investigation of planar noise coupling with respect to the separation distance between the planes and use of decoupling capacitors is presented. The validity of the developed model is successfully tested on sample structures.
