摘要：
The purpose of the present invention is to reduce the noise of an analog circuit of a radio-use semiconductor apparatus. A power supply voltage is supplied to a low-noise amplifier 12 and a partial circuit of a stereo demodulation circuit 16 from an analog-use power supply. A power supply voltage is supplied to a digital circuit 19, an MPXPLL 17, and pilot signal detection circuit 18 of the stereo demodulation circuit 16 from a digital-use power supply that is separate from the analog-use power supply. This configuration prevents noise generated in a digital circuit from propagating to the analog circuit within the stereo demodulation circuit.
