Abstract:
1. An integrated circuit device comprising: a digital power supply regulation circuit that regulates a digital power supply voltage; an analog power supply regulation circuit that regulates an analog power supply voltage; a control logic circuit that includes logic cells and operates based on the digital power supply voltage that is regulated by and supplied from the digital power supply regulation circuit; an analog circuit that includes at least a comparator or an operational amplifier and operates based on the analog power supply voltage that is regulated by and supplied from the analog power supply regulation circuit; and a power supply wiring region, at least a digital power supply line that supplies the digital power supply voltage that is regulated by the digital power supply regulation circuit and an analog power supply line that supplies the analog power supply voltage that is regulated by the analog power supply regulation circuit being provided in the power supply wiring region, the digital power supply regulation circuit, the analog circuit, and the analog power supply regulation circuit being disposed in a first direction with respect to the control logic circuit; and the power supply wiring region being formed along a second direction in a region between the control logic circuit and the digital power supply regulation circuit, the analog circuit, and the analog power supply regulation circuit, the second direction being a direction perpendicular to the first direction.
