Effect of Stitching and Decoupling Capacitors in the Split Power Distribution Network

Signal integrity problems and their possible solutions are addressed in this paper for the split power plane of the high-speed digital systems. Stitching and decoupling capacitors are proved to be very effective for reducing signal noise, ground bounce as well as electromagnetic radiation from the split power plane. Simulations based on 3D-Finite Difference Time Domain (FDTD) method are utilized for the analysis of practical high frequency multi-layered PC main board
