| 摘要 |
It is an object of the present invention to provide a semiconductor device that has a simple circuit structure, a small scale, and low power consumption, and can generate a desired clock signal. The semiconductor device has a clock generation circuit which generates a clock signal by dividing a modulated carrier wave, a divider circuit which generates a first divided signal by dividing a carrier wave, and a correction circuit which generates a second divided signal by further dividing the first divided signal, and has a function of performing correction for inverting the second divided signal in a period corresponding to a half period of the clock signal during modulation of the carrier wave and selecting whether the correction is performed or not.
