TLDR
A 60-GHz injection-locked frequency divider fabricated in 65nm CMOS and operating at 1.2V consumes 1.65mW excluding buffers and biasing circuits, and has a measured locking range of 48.5–62.9GHz with 0dBm input power.Abstract:
A 60-GHz injection-locked frequency divider (ILFD) fabricated in 65nm CMOS and operating at 1.2V consumes 1.65mW excluding buffers and biasing circuits, and has a measured locking range of 48.5–62.9GHz (25.9%) with 0dBm input power. The core ILFD area is 0.0157mm2. The large locking range is attributed to the use of the multi-order LC oscillator topology.read more
