PLL is one of important circuit in RF circuits. PLL is composed prescaler is large power consumption. Injection-Locked-Frequency-Divider (ILFD) is prescaler for suppressing power consumption. But, ILFD has narrow locking range so operation range is limited. In this paper, we propose method to expand locking range of ILFD is inserted differential transistor to injection lock between ring oscillator outputs, injecting the same signal to tail transistor. Key Words : Injection Locked Frequency Divider, Ring Oscillator, RF, CMOS
