<p>A feeding device for a printed circuit board is used particularly for high fidelity and low noise amplifier etc. For minimizing the non-linear distortion occuring on the power line the feeding device comprises a distributed capacity element (14) consisting at least of a first and the second conductive strips (11, 12) separated from each other by a low loss dielectric layer, leading-out terminals (A, B, C) provided to said first conductive strip (11), a power source connected to at least one leading-out terminal (C), an electrolytic condenser (Ci) connected to the power source, and at least one non-polarized condenser (C2) connected to the electrolytic condenser (C1) in parallel, said second conductive strip (12) being connected to an earthing circuit. The distributed capacity element (14) is formed in an oblong shape by folding and coiling up the layered first and the second conductive strips (11, 12), and leading-out terminals connected to the strips (11, 12). Said element (14) is enclosed in an container or encapsulated by plastic material.</p> |
