Abstract :
This brief presents a multimodulus frequency divider with division ratio between 64 and 127 fabricated in 90-nm CMOS. By using a load-switching technique, high operating frequency, and low power static divider was achieved. The divider consists of six 2/3 divider stages. The maximum operating frequency is 4.7 GHz with current consumption 2.3 mA at low voltage supply 1.2 V and rms cycle-to-cycle jitter lower than 1 ps
