Abstract :
A 30-GHz wide locking-range (25%) injection-locked frequency divider (ILFD) with small power consumption (1.86 mW) is presented. The locking range of the ILFD is extended by reducing the quality factor of resonant tank. Besides, the output power level of second harmonic is lower than that of fundamental component by 37 dBc due to the new output buffer where the second harmonic can be cancelled. The proposed wideband ILFD is implemented in 0.13-mum standard CMOS process. It achieves a wide locking-range of 6.2 GHz (25 %) without any frequency tuning mechanism under the small power consumption of 1.86 mW and the highest figure-of-merit of 12.4 (%/mW) among all reported state-of-the-art CMOS ILFD.
