A wide-locking-range and low-power injection-locked-frequency-divider (ILFD) using direct injection in dual-step mixing is proposed to widen locking range (LR) of divide by 4 and 6 operations. Two main advantages over the previously-reported progressive mixing ILFD are less headroom required and less sensitivity over large injection amplitude. This work achieves the widest LR reported of 4.3GHz for divide-by-6 and 5.7GHz for divide-by-4 operation while consuming 3.1mW without frequency tuning. The divide-by-4 and divide-by-6 operation of this ILFD can cover the required frequency range for 60GHz wireless standards.
