Present paper proposes an injection locked oscillator under multiple injection sources. An injection locked frequency divider (ILFD) under multiple injections with harmonic components 2ω 0 and 3ω 0 improves the phase noise performance of the oscillator substantially compared to the single source injection. Simulation results show that at the supply voltage of 2.4V, at the injected signal power of 0dBm the simulated phase noise of the free running ILFD oscillating at frequency of 2.72 GHz is -108.5dBc/Hz at 1.04MHz offset frequency and the phase noise of the locked oscillator output being -123.24dBc/Hz showing an improvement of 14.72dBc/Hz with 6.4mW of power consumption
