Abstract
A circuit includes a first ring oscillator with a plurality of stages, each coupled via a voltage follower cross-coupling to a plurality of stages of a second ring oscillator. Further ring oscillators may be coupled to the first ring oscillator and the second ring oscillator. Additionally, the voltage follower cross-coupling for each of the stages may include one or more first voltage follower having a first strength, and one or more second voltage follower having a second strength different than the first strength.
