A wide locking range and low phase noise injection‐locked frequency divider has been developed by CMOS 0.13‐μm technology. The proposed differential complementary injection‐locked frequency divider (CILFD) consists of five‐stage complementary inverter type connection. The differential input and output are implemented using auxiliary cross‐coupled inverters. The measurement results show a divide‐by‐5 division ratio and a locking range from 1.5 to 4.5 GHz with an input power lower than −5 dBm. The power consumption of CILFD is 1.0 mA from 1.4‐V power supply when it locked at 3‐GHz input signal. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:31–34, 2014
