INTEGRATED CIRCUIT WITH RING OSCILLATOR |
摘要 |
An integrated circuit includes a ring oscillator including delay cells having a delay value and configured to generate two or more periodic waves, a first phase controller configured to compare the phase of a first selected periodic wave to the phase of a reference wave and change the delay value of the delay cells from a first delay value to a second delay value based on a first comparison signal corresponding to a phase difference between the first selected periodic wave and the reference wave, and a second phase controller configured to compare the phase of a second selected periodic wave to the phase of the reference wave and restore the delay value of the delay cells from the second delay value to the first delay value based on a second comparison signal corresponding to a phase difference between the second selected periodic wave and the reference wave. |
