Each set of circuits comprises a first circuit, a second circuit and a third logic device. The first circuit and the second circuit respectively comprise a first logic device and a second logic device connected to the first logic device. The clock signal frequency in each set of circuits is half of a clock frequency. In each set of circuits, the phases of input signals of the first circuit and the second circuit are different. The phases of input signals of the first circuits in the sets of circuits are the same, and the phases of input signals of the second circuits in the sets of circuits are the same. The outputs of the first circuits and the second circuits are combined by means of the third logic devices. The switch driver reduces the clock signal frequency of each set of circuits by half, and accordingly reduces the data rate of each channel in the switch driver, thereby reducing power consumption, doubling data cycle, making data acquisition easier, and reducing the timing requirements accordingly.
