| Summary: | −1−2−3 −1 −2 −1 −2 −1 −2 −1 −2 In order for circuit blocks to composed by the CMOS process, and analog lines , and connected thereto not to overlap on the layout, the analog lines and are wired so that such lines roundabout the layout of the AM/FM common circuit block . Through this, the distance of the signal line within the AM/FM common circuit block and the analog lines and can become as long as possible, the signal line within the AM/FM common circuit block and the analog lines and would not be coupled via parasitic capacity, and mutual interference occurring between the signal line and the analog lines and can be suppressed. In another aspect, a semiconductor integrated circuit with a CMOS structure includes an analog circuit and a feedback loop, wherein an analog signal line for the feedback loop is wired outside a layout of the analog circuit. |
