In this paper, a multi-mode magnetically coupled and tuned inductive peaking technique with impedance transforming capability is proposed to achieve a wider operational locking range in the injection locked frequency divider (ILFD) for low injected power levels. Fabricated in 65 nm CMOS process, the proposed ILFD operating at 60 GHz, achieves a locking range of 16.3% from 53.2 to 63 GHz with a low injected power of −10 dBm. Occupying a small area of 0.0288 mm 2 , the ILFD delivers an average single-ended output power of −6 dBm with a dc power consumption of 3.7 mW from a 1.2 V supply voltage. The power efficiency (P out /P dc) of the proposed ILFD is 6.8%. INDEX TERMS 60 GHz, divide-by-2, direct injection locked frequency divider (ILFD), inductive peaking, multi-coupled coils, multi-mode.
