Abstract
Based on a detailed analysis of harmonic generation
in ring-based injection-locked frequency dividers (ILFDs), this
article shows that concurrent injection signals can be generated
in these stages by driving both tail and direct injectors with the
same input signal. Based on this result, a novel ring-based divide-
by-five ILFD is presented, where multi-injection is reinforced
by a dual-path scheme, largely broadening the locking range
with no penalty in power dissipation. The stage, implemented i
