选择性

A frequency divider, comprises: an inverting unit comprising an input, and an output; and a plurality of switch inverters in series, having at least a first switch inverter and a last switch inverter; each switch inverter comprising two inphase switches, in which the first switch inverter is connected to the output of the inverting unit, and the last switch inverter is connected to the input of the inverting unit; wherein the two inphase switches of each of the switch inverters are respectively supplied by a first voltage and a second voltage, any two of the adjacent switch inverters are respectively controlled by two inverted clocks, thereby the two inphase switches are selectively turned on synchronously and turned off synchronously.

反相单元包含输入端以及输出端；串联的多个切换反相器，具有至少一第一切换反相器以及最终切换反相器，每一切换反相器包含两个同相开关，其中第一切换反相器连接于反相单元的输出端，且最终切换反相器连接于反相单元的输入端；每一切换反相器的同相开关分别由第一电压与第二电压供电，任何两个相邻的切换反相器分别受控于两个反相时钟，因此该两个同相开关是选择性同步开启及同步关闭的。
