Abstract
PURPOSE:To adjust necessary power consumption, and to decrease the kinds of parts, by connecting a common gate connecting line of a stndard cell to a suitable voltage source by a wiring mask of the same metal, in accordance with a limit of power consumption, etc. depending on the number of the standard cells to be used, and its use. CONSTITUTION:The gates of QL31, QL33, QL41, QL43, etc. functioning as a part of load elements of standard cells 30, 40, etc. are connected in common to an electric power supply line VGG, and a voltage-dividing circuit 20 for supplying voltage to the electric power supply line VGG is provided. In this state, in case when an integrated circuit device is constituted by changing a connecting pattern between the mutual standard cells 30., 40, etc., the power consumption is adjusted by connecting suitable output terminals VG1-VG5 of the voltage-dividing circuit 20, and the VGG line so as to match the number of the standard cells to be used 30, 40, etc. Also, although the standard cell 40 uses all the load elements, the standard cell 30 uses a part of the load elements, therefore, the power consumption is reduced, and the power consumption is adjusted by voltage of VGG in a state that the ratio of both the cells remains kept constant.
