摘要

This study proposes a new divide-by-3 CMOS injection locked frequency divider (ILFD) fabricated in a 0.18-μm CMOS process and describes the operation principle of the ILFD. The ILFD circuit is realized with a Hartley CMOS LC-tank oscillator with two injection MOSFETs. The self-oscillating VCO is injection-locked by third-harmonic input to obtain the division order of three. Measurement results show that at the supply voltage of 1.5 V, the free-running frequency is from 3.86 to 4.27 GHz. At the incident power of 6 dBm, the locking range is from the incident frequency 12.13-12.86 GHz.
