A low power wide locking range divide-by-4 injection-locked frequency divider (ILFD) is proposed in the letter and was implemented in the TSMC 0.18 mu m SiGe BiCMOS process. The divide-by-4 ILFD uses a cross-coupled voltage-controlled oscillator with an active inductor and a three-transistor composite consisted of two nMOSFETs and one pMOSFET to serve as an injection device with the function of linear and nonlinear mixers. At the supply voltage of 1.5 V and at the incident power of 0 dBm, the operation range of the divide-by-4 is 2.3 GHz, from the incident frequency 14.5 to 16.8 GHz, the percentage is 14.7%. The locking range of the divide-by-4 is 1.7 GHz, from the incident frequency from 14.6 to 16.3 GHz, the percentage is 11%. The core power consumption is 1.5 mW. The die area is 0.465 x 0.317 mm2.
