Abstract :
This letter presents a W-band wide-locking range divide-by-three injection-locked frequency divider (ILFD) implemented in 90 nm digital CMOS technology. The second-harmonic generator (SHG) is proposed to boost the second harmonic signal for effective harmonic mixing and extend the locking range of the frequency divider. The power consumption of the divider is 10.8 mW and the operation frequency of the input signal ranges from 73.1 to 84.3 GHz. To the authors´ knowledge, this work is the first W-band divide-by-three ILFD with the locking range wider than 10%.
