Patent

CA 2190458

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.

L'invention concerne un mécanisme de couplage présentant une capacité appartenant à une plaquette avec un circuit imprimé. La plaquette (1) se compose de plusieurs couches électriquement conductrices (50e, 50g) séparées par des couches électriquement isolantes (50eg). Une extension de surface d'une couche liée présentant un potentiel de référence (50e), une extension de surface opposée d'une couche liée d'une tension d'alimentation (50g) et une distance choisie entre lesdites couches sont adaptées pour remplir une fonction de condensateur pour lisser les pics de tension. Cela permet d'obtenir une tension d'alimentation en courant continu constante autour des circuits (2) fixés sur ladite plaquette même lors de variations de courant rapides lors de l'activation desdits circuits et/ou composants.
