We present a 31–45.5 GHz injection-locked frequency divider(ILFD) implemented in a standard 90-nm CMOS process. To reduce parasitic capacitance and increase the operating frequency, an NMOS-only cross-coupled pair is...

This paper proposes a direct injection-locked frequency divider(ILFD) with a wide locking range in the Ka-band. A complementary cross-coupled architecture is used to enhance the overdriving voltage of the switch tra...
