Power control circuit, method of controlling power control circuit, and DLL circuit including power control circuit |
摘要 |
A power control circuit includes a check unit that receives a reference clock and generates a check signal for cyclically activating a feedback loop of a DLL circuit, a phase detecting unit that detects a phase difference between the reference clock and a feedback clock, and generates a phase difference detection signal, and a signal combining unit that generates a power cutoff signal in response to a locking completion signal, the check signal, and the phase difference detection signal. |
