In this paper, a 30GHz wide locking-range (26.2GHz-35.7GHz) directs Injection-Locked Frequency Divider (ILFD), which operating in the MilliMeter-Wave (MMW) band, is presented. The locking range of the ILFD is extended by using differential injection topology. Besides, varactors are used in RLC resonant tank for extending the frequency tuning range. The post simulation results show that a wide locking-range of 9.5GHz (30.7%) is achieved. When the VCO output frequency varies from 26.85GHz to 34.42GHz, the proposed ILFD can achieve divide-by-two correctly.
