A W-Band Divide-by-Three Injection-Locked Frequency Divider With Injection Current Boosting Utilizing Inductive Feedback in 65-nm CMOS

A compact W-band divide-by-three injection-locked frequency divider (ILFD) is presented in 65-nm CMOS technology. To provide a wide locking range, we propose inductive feedback to boost the injection current. With the proposed approach, the locking range of the ILFD can be wider than 10% without any varactor and additional power dissipation which is more than three times the locking range compared...
