Multilayer printed circuit for signals whose rise time is less than one nanosecond. The conductive layers are stacked in the following order starting at any of the outer faces: connecting layer, ground layer, supply layer, ground layer. Thus, connections may be made by means of fixed-impedance microstrip lines and supply by means of very low impedance strip lines (less than a fraction of 1 ohm).
