## Abstract A 20–30 GHz divide‐by‐3 ring‐based injection locked frequency divider (ILFD) using NMOS loads for a wide locking range has been developed in a commercial 0.13‐μm Si RFCMOS technology.The ILFD shows a locking range up to 7.5 GHz (20.8−28.3 GHz, 30.5%) and operation range of 10 GHz (20.8–
