Abstract: Provided is a control device for an internal combustion engine capable of avoiding deterioration of combustion and reliably suppressing synthetic noise of a high pressure fuel pump and a fuel injection valve without affecting an operating state of the internal combustion engine. Therefore, when it is determined that there is synthetic noise of a high pressure fuel pump and a fuel injection valve, an operating angle of a variable valve mechanism provided in the internal combustion engine is made variable while satisfying a fuel injection request of the fuel injection valve.

Abstract: On a transistor layer having arranged thereon multiple transistors each including a drain, a source, and a gate, metal interconnection layers serving as input side interconnection layers connected to the drains of the respective transistors and metal interconnection layers serving as output side interconnection layers connected to the sources of the respective transistors are arranged in parallel. Also provided are a plurality of through holes connecting the metal interconnection layers serving as input side interconnection layers to the drains of the respective transistors and connecting the metal interconnection layers serving as output side interconnection layers to the sources of the respective transistors. Resistance values of the plurality of through holes are changed along an arranging direction of the input side interconnection layers and the output side interconnection layers. Accordingly, current densities of the transistors arranged to be distributed in a two-dimensional manner can be uniform.
