A frequency divider has an inverting unit and a plurality of switch inverters in series. Each switch inverter comprises two inphase switches and is controlled by a clock. The two inphase switches of each switch inverter are respectively supplied by a first voltage and a second voltage, while any two switch inverters in series are respectively controlled by two inverted clocks. The two inphase switches are selectively turned on and off synchronously.
