A dual feed-forward ring oscillator is provided to output a high output frequency without decreasing the number of delay stages by using a dual feed-forward loop between delay stages. First to eighth delay stages(110-180) are directly connected to one another. The eighth to first delay stages are cross-linked with one another. A main input terminal of first and second path input terminals of the respective delay stages is connected to first and second path output terminals of a previous delay stage. The main input terminal of the first and second path input terminals of the first delay stage is connected to first and second output terminals of the eighth delay stage, respectively. A pre-in input terminal of the first and second path input terminals of the respective delay stages is connected to the first and second path output terminals of a second-previous delay stage. |
