Description
Summary:In this paper, a multi-mode tuned inductive peaking technique with impedance transforming capability based on multi-coil magnetic coupling is proposed to widen the operational locking range of injection locked frequency divider (ILFD) with low injected power levels. Fabricated in 65nm CMOS process, the proposed ILFD operating at 60 GHz, achieves an locking range of 16.3 % from 53.4 GHz to 62.9 GHz with a low injected power of −12 dBm. Occupying a small area of 0.0288 mm 2 , the ILFD has a DC power consumption of 3.7 mW from a 1.2 V supply voltage.
