Abstract
A 50-to-62GHz injection-locked frequency divider (ILFD) with transformer feedback technique is designed in 0.13-μm CMOS technology for wide locking range. The measurement results show that the free-running frequency is 55.3 GHz and the total locking range is 12GHz (≫20%) at the input power level of 0dBm while consuming 10.8mW from a 0.9V power supply. The phase noise of the divider is −124.93dBc/Hz at 1MHz offset from the carrier. This wide locking range ILFD is suitable for integration into a phase-lock-loop (PLL) system because of its small size and no need of extra control signal.
