Abstract :
A 54.6 GHz divide-by-3 injection locked frequency divider with low power consumption is presented. A resistive feedback is implemented to achieve a stable dc input and higher injection efficiency. Compared with the conventional design, it exhibits a better supply voltage rejection and wider locking range while a small silicon area is maintained. Fabricated in a TSMC 65 nm bulk CMOS process, this divider operates from 48.8 to 54.6 GHz and consumes 3 mW from a 0.9 V supply.
