Zusammenfassung:A four-stage gated ring oscillator having four gated amplifiers configured in a ring topology and comprising a first pair of gated amplifiers, controlled by a first phase of an two-phase input clock, interleaved with a second pair gated amplifiers, controlled by a second phase of the two-phase input clock; and two cross-coupling latches configured to provide cross-coupling between the first pair of gated amplifiers and the second pair of gated amplifiers.
