An LC injection locked frequency divider (ILFD) in CMOS technology is designed. By adopting the direct injection of signal into the resonation tank, the locking range of the ILFD is improved. For the purpose of reducing the power consumption, the complimentary topology is adopted in this work and also the voltage swing of the ILFD is optimized. The simulation results indicate that the ILFD has a wide locking range from 9.3 GHz to 11 GHz, and the core of the ILFD consumes 100 μA under 3.3 V power supply.
