A first shifting unit outputs first shifting signals using at least one of periodic signals. A control signal generating unit outputs multiplexing control signals using an inverted clock signal; a second shifting unit that outputs second shifting signals using the at least one of periodic signals. A correcting unit outputs correction signals having an intermediate phase between the phase of the first shifting signals and the phase of the second shifting signals on the basis of a bias signal applied thereto. A combination unit combines the first shifting signals and the correction signals to output combined signals. A multiplexing unit selectively outputs the combined signals on the basis of multiplexing control signals. A driving unit drives the clock signal and the inverted clock signal on the basis of the output of the multiplexing unit
