Latest Patents
Qingxiang Dong holds a patent for a phase-locked loop device. This device includes a frequency-locked loop circuit and a phase-locked loop circuit. The frequency-locked loop circuit features a delay generator circuit and a frequency-phase detector. The delay generator circuit generates a ramp signal based on the feedback clock signal and compares it with multiple reference voltages to produce several delayed feedback clock signals. The frequency-phase detector incorporates a dead zone control mechanism that generates a locking signal based on the phases of the reference clock signal and the delayed feedback clock signal, automatically switching the dead zone on and off. The phase-locked loop circuit generates the first output current according to the phase difference between the reference clock signal and the feedback clock signal.
