Abstract—A new injection-locked frequency divider (ILFD)
circuit topology, by combining the strengths of LC type ILFD
(LC_ILFD) and ring oscillator type ILFD (RO_ILFD), is pro-
posed to achieve high speed, low power, wide locking range and
accurate quadrature output phases. The frequency-division cri-
terion is analyzed and agrees well with simulation results. The
phase-locking mechanism is also investigated
