Abstract

A 60-GHz injection-locked frequency divider (ILFD) with quadrature outputs is designed in 90-nm CMOS technology. An adaptive-coupling scheme is proposed to enlarge the phase shift for a wide-band locking range. The measured results exhibit an input locking range of 12.1GHz or 20.5%from 52.7 to 64.8GHz at an incident power of 0dBm. The core circuit consumes 8.6mW from a 1.2V power supply and occupies an area of 360μm×230μm².
