Abstract
A double phase comparator sets both first and second signals to an “L” level in order to delay a phase of a feedback clock signal when the feedback clock signal is at the “H” level and the “L” level at the rising and falling edges of an internal clock signal, respectively. The double phase comparator also sets both first and third signals to the “L” levels in order to advance a phase of a feedback clock signal when the feedback clock signal is at the “L” level and the “H” level at the rising and falling edges of an internal clock signal, respectively. Moreover, the double phase comparator sets the first signal to the “H” level in order to stop a phase control of the feedback clock signal when the feedback clock signal is at the same level at the rising and falling edges of an internal clock signal.
