A injection-locked frequency divider (ILFD) with a 0.8-V current mode logic (CML) frequency divider are presented in this paper. These two frequency dividers are fabricated and integrated in 0.13-μm CMOS technology. The proposed ILFD adopts the admittance-transforming to widen the locking range. To achieve low-supply-voltage in CML frequency divider, the transconductance stage of CML divider is replaced by the inductance. Under 0 dBm injected power, the measured results show that the proposed ILFD have 22.8 % bandwidth from 40.5-to-50.9 GHz. Furthermore, the divider-by-four frequency divider composed of an ILFD and CML divider are measured with locking range from 42 to 45 GHz. The ILFD and CML divider consume 3.6 mW and 8 mW dc power from 0.6 V and 0.8 V supply voltage, respectively.
