ABSTRACT This letter presents a wide‐locking range CMOS divide‐by‐3 injection‐locked frequency dividers (ILFD) using single‐ended injection signal. The fabricated 0.18 μm CMOS ÷3 ILFD uses cross‐coupled switching transistors, single‐injection MOSFET, and a dual‐resonance RLC resonator. The consumed power of the ÷3 ILFD core is 7.97 mW at the DC drain‐source voltage 0.76 V. At an external injected signal power P inj = 0 dBm, the measured locking range is 2.97 GHz (25.25%) from 10.28 to 13.25 GHz and the operation range is 5.17 GHz (48.5%) from 8.08 to 13.25 GHz. © 2015 Wiley Periodicals, Inc.
