  • Coupling device presenting and/or dominating a capacitance belonging to a board with a printed circuit
    Patent number: 5815373
    Abstract: The invention relates to a coupling device presenting a capacitance belonging to a board with a printed circuit, where said board (1) consists of several electrically conducting layers (50e, 50g) with electrically isolating layers in between (50eg). A surface extension of a reference potential related layer (50e), an opposite surface extension of a supply voltage related layer (50g) and a chosen distance in between said layers are adapted to form a capacitor function to smooth voltage spikes so that the DC-supply voltage can be constant around circuits (2) mounted on said board even at rapid current variations as said circuits and/or components are activated.
