Abstract
One end of a power-supply bus is connected to a power supply through a ferrite bead. The power-supply bus is connected to power-supply terminals. The power-supply terminals are connected at positions in such a manner that a terminal with a higher intensity is connected closer to the other end of the power-supply bus. Ground terminals are connected to ground. Capacitors are bypass capacitors or decoupling capacitors, for example, and connected between respective power-supply terminals and ground.
Claims20
A device comprising:
- a plurality of power-supply terminals;
- an integrated circuit that is connected to said plurality of said power-supply terminals;
- and
- a power-supply bus having one end connected to a power supply, and one other end,
- said plurality of power-supply terminals being connected to said power-supply bus in such a manner that one of the plurality of power supply, terminals, relative to, other one of the plurality of power supply terminals, having noise of a higher intensity contained in a current flowing in itself is connected to said power-supply bus at a position closer to said one other end.
