摘要:
A phase shifter includes a phase shifting unit for operating at a timing at which a clock signal becomes equal to or greater than a threshold value and outputting periodic signals having phases shifted by 90 degrees from each other; a DC voltage setting unit for setting a voltage value of a DC component of the clock signal input into the phase shifting means; and a clock signal slope varying unit for varying a slope of a rising edge of the clock signal.
