Abstract
A phase detection circuit may include an edge trigger circuit, a strobe generation circuit and a phase detector. The edge trigger circuit generates a falling clock signal and a rising clock signal based on a reference clock signal and a target clock signal. The strobe generation circuit generates a falling strobe signal and a rising strobe signal having pulse widths varying based on a phase relationship between the reference clock signal and the target clock signal. The phase detector generates a phase detection signal based on the falling clock signal, the rising clock signal, the falling strobe signal and the rising strobe signal.
