Abstract

A 60-GHz injection-locked frequency divider (ILFD) is presented. A multi-order LC oscillator topology is proposed to enhance the locking range of the divider. A design guideline is described based on a theoretical analysis of the locking range enhancement. A test chip is fabricated in 65 nm CMOS. Measured locking range with 0 dBm input power is 48.5-62.9 GHz (25.9%), which is 63.6% wider compared to the previously reported ILFD. Power consumption excluding buffers and biasing circuits is 1.65mW from 1.2V supply. The core ILFD area is 0.0157mm² even with an extra pair of inductors.
