70GHz CMOS Harmonic Injection-Locked Divider

A 70GHz CMOS harmonic injection-locked divider (HILD) is presented, where a third-harmonic mixer is realized by a differential-voltage-driven MOSFET. The chip is fabricated in a 6M 90nm CMOS process. A maximum operating frequency of 71.6GHz with a locking range of 12% at a supply voltage of 0.5V is measured. The chip consumes 2.75mW
