A new low power wide locking range divide-by-3 injection-locked frequency divider (ILFD) using a standard 0.13 mu m CMOS process is presented. The push-push ILFD circuit is realized with a cross-coupled n-core MOS LC-tank oscillator with linear mixer to extend the locking range. The power consumption of the ILFD core is 2.05 mW. The divider's free-running frequency is tunable from 4.37 to 5.43 GHz by tuning the varactor's control bias, and at the incident power of 0 dBm the maximum locking range is 2.6 GHz (16.5%), from the incident frequency 14.5 to 17.1 GHz. The operation range is 5.1 GHz (35.1%), from 12.0 to 17.1 GHz.
