A 2.9mW 53.4–79.4GHz frequency-tracking injection-locked frequency divider with 39.2 locking range in 65nm CMOS

摘要

A frequency-tracking technique together with a single-coil distributed differential inductor is proposed to enhance the locking range of mm-Wave injection-locked frequency dividers (ILFDs). Implemented in a 65nm CMOS process, the proposed ILFD measures a locking range of 39.2% from 53.4GHz to 79.4GHz and consumes 2.9mW from a 0.8V supply corresponding to FOM of 8.97 GHz/mW while occupying an area of 0.126 mm².
