Abstract
A variation in threshold may be suppressed by structuring an analog switch by a MOS transistor and forming a signal synchronized to a clock by making the clock which is a common signal in continuity or discontinuity. An object of the present invention is to reduce the variation in the signal synchronized to the clock by the variation in threshold of the MOS transistor in a circuit which is synchronized to the clock.
