A W‐band injection‐locked frequency divider (ILFD) with modified transformer coupling resonant is demonstrated and implemented in a 40‐nm CMOS technology. The locking range and operation frequency of the ILFD is improved without increasing chip area or circuit complexity. The measured locking range of the ILFD covers from 86 to 104 GHz. The measured phase noise of the modified W‐band ILFD is −114.89 dBc/Hz at 1 MHz. The ILFD also attains a figure of merit normalized (FoM) of 243.1.
