ABSTRACT:
An electronic circuit device having a power wiring resonance inhibition function includes a plurality of electronic circuit elements, and a wiring board having the electronic circuit elements disposed thereon. The wiring board includes a plurality of planar power supply wires for supplying power to the electronic circuit elements. The planar power wires include a pair of planar power supply wires for supplying power to the electronic circuit elements at a predetermined voltage. The electronic circuit device also includes a plurality of damping elements disposed at a plurality of positions on the wiring board. The damping elements are connected between the pair of planar power supply wires at a plurality of positions on the pair of planar power supply wires. The damping elements reduce power supply system impedance and inhibit power wiring system resonance, thereby reducing supply voltage fluctuation caused by the power wiring system resonance and noise caused by the supply voltage fluctuation.
