A capacitor array 15 is formed from a board 16 having multiple layers 17, 18, 19 with conductive paths 20, 30, 40, 21, 31, 41, 22, 32, 42, 62, 72, 82 on selected layers. Paths across the layers are aligned and sufficiently close that each aligned array e.g. 20, 30, 40 acts as a single solid capacitor plate. Capacitive coupling between pairs of plates e.g. 20, 30, 40 and 21, 31, 41 produces crosstalk. A conductor of a connector may be connected to each plate, for example by a through-plated vias T, R and short traces 28, 29. The crosstalk between the plates is equal and opposite to the crosstalk between the conductors thereby cancels the crosstalk of conductors. Crosstalk cancellation between adjacent pairs of plates may occur. |
