发明名称 DIVIDER CIRCUIT
摘要 A divider circuit includes a shift register which generates 2X (X is a natural number greater than or equal to 2) pulse signals in accordance with a first clock signal or a second clock signal and outputs them, and a divided signal output circuit which generates a signal to be a third clock signal with a cycle X times longer than a cycle of the first clock signal in accordance with the 2X pulse signals and outputs it. The divided signal output circuit includes X first transistors which control whether voltage of the signal to be the third clock signal is set to first voltage; and X second transistors which control whether voltage of the signal to be the third clock signal is set to second voltage.
