发明名称 CLOCK PHASE SHIFT DETECTOR
摘要 A clock phase shift detector circuit may include a phase detector that receives a first and a second clock signal, whereby the phase detector generates a phase signal based on a phase difference between the first and the second clock signal. A first integrator is coupled to the phase detector, receives the phase signal, and generates an integrated phase signal. A second integrator receives the first clock signal and generates an integrated first clock signal. A comparator is coupled to the first and the second integrator, whereby the comparator receives the integrated phase signal and the integrated first clock signal. The comparator may then generate a control signal that detects a change between the phase difference of the first and the second clock signal and an optimized phase difference based on an amplitude comparison between the integrated phase signal and the integrated first clock signal.
