Popis:	In a high-speed multi-layer PCB (printed circuit board) design with multiple power layers, signal trace placement can be an important issue. Studies on a multi-layer test board are reported in this work. Single-ended high-speed signals that use the power layers as reference (return) may suffer extra loss in some frequency ranges due to the displacement current path from the power layer to ground. "Reference" capacitors are recommended as a solution to mitigate this effect. Differential traces do not suffer this extra loss. However, transmission loss and mode conversion of a differential trace may be affected by its layer position. The traces immediately adjacent to the ground layer showed the best performance in this particular test board.
