Abstract
According to one embodiment of the invention, a ring oscillator is provided that includes a number of stages, each of the stages being coupled to an output of at least two previous stages. This architecture is referred to hereinafter as a “feed forward” architecture, as signals are fed forward to further stages beyond a consecutive stage. Any number of stages may be used. This architecture represents a new topology for ring oscillator design, as ring oscillators generally include consecutive stages that each have an input from the previous stage only. In general, such an architecture achieves higher frequencies than oscillators without feed forward paths.
