A Current Reused Divided-by-Two Frequency Divider

Abstract:

In this paper, a low power dissipation divide-by-two frequency divider is presented. The master latch and the slave latch of the divide-by-two frequency divider are stacked in cascode to reuse the current. The frequency divider can operate with only half the current of a conventional divider. A divide-by-two frequency divider based on the proposed topology is designed and simulated in a 0.18μm 1P6M CMOS process. Simulation results show the frequency divider can operate up to 11GHz with only 0.66mW power dissipation under 1.8V supply voltage. And it also demonstrates good phase noise performance.
