Problems solved by technology

In this case, when the noise of the digital circuit is transmitted to the analog circuit, there is a problem that the analog circuit may malfunction
On the other hand, in order to reduce the adverse effects of such noise, the distance between the digital circuit and the analog circuit will be widened, which will lead to an increase in the area of ​​the integrated circuit device.

Abstract

The present invention discloses an integrated circuit device capable of reducing noise infection and improving layout efficiency. The integrated circuit device includes a digital power supply regulation circuit, an analog power supply regulation circuit, a control logic circuit, an analog circuit, and a power supply wiring region. A digital power supply line which supplies a digital power supply voltage and an analog power supply line which supplies an analog power supply voltage are provided in the power supply wiring region. The digital power supply regulation circuit, the analog circuit, and the analog power supply regulation circuit are disposed in a first direction with respect to the control logic circuit. The power supply wiring region is 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.

Description

technical field [0001] The present invention relates to integrated circuit devices and electronic equipment. Background technique [0002] In recent years, the technology of non-contact power transmission (non-contact power transmission) that enables power transmission without contact of metal parts by using electromagnetic induction has attracted attention. As an example of application of this non-contact power transmission, there is a charging technique for a mobile phone or a household device (for example, a handset of a telephone) in the prior art. [0003] There is Patent Document 1 as a prior art of contactless power transmission. In Patent Document 1, a capacitor connected to the output of a power transmission driver and a primary coil constitute a resonant circuit, and power is supplied from a power transmission device (primary side) to a power reception device (secondary side, user side). In addition, there is Patent Document 2 as a prior art of a semiconductor po...
