Abstract
A frequency-tracking technique is proposed to
enhance the locking range of m illimeter-wave (mmW) injec-
tion-locked frequency divide rs (ILFDs). An improved model is
introduced for direct-injection ILFDs, based on which both the
phase and gain conditions are an alyzed and discussed. Moreover,
a method of admittance locus is applied to obtain the design
intuition for optimization and t o predict the locking range accu-
rately. Finally, with the proposed model and design methodology,
a frequency-
