A CMOS Multi-Phase Injection-Locked Frequency Divider for V-Band Operation

An inductor-less injection-locked frequency divider for high-speed frequency synthesis at V-band is presented. It achieves division by six and operates up to 65 GHz. In addition, it can achieve division ratios of four and two when 44 GHz or 22 GHz input signals are applied, respectively. Implemented in a 0.13 mum digital CMOS technology, the divider draws an average current of 18 mA, and the core area is 0.026 mm² .
