Ultra-Wide Locking Range Regenerative Frequency Dividers With Quadrature-Injection Current-Mode-Logic Loop Divider

Design of voltage-controlled oscillators and frequency dividers for 60 GHZ wireless communication applications

“…However, those methods require extra circuits and power consumption. A static frequency divider which can be viewed as a two-stage ring oscillator is inherently able to provide highly matched quadrature outputs [112]. However, static frequency dividers usually suffer from large power consumptions.…”
