Abstract :
A voltage controlled differential injection locked frequency divider (VCDILFD) with a large locking range is designed in a 0.24 μm CMOS technology. A 29% locking range is achieved by an optimal inductor design and also by employing high Q accumulation mode MOS varactors to change the free-running oscillation frequency of the divider. The measurement results show frequency division at 5 GHz, with more than 1 GHz locking range and power consumption of less than 1 mW
