Latest Patents

One of Hairong Yu's latest patents focuses on reference clock switching in phase-locked loop circuits. This innovative clock generator circuit includes a multiplex circuit and a phase-locked loop circuit. The multiplex circuit generates a reference clock signal for the phase-locked loop circuit by selecting one of several different clock signals. When the reference clock signal switches from one clock signal to another, the phase-locked loop circuit disables phase-locking and enters a frequency acquisition mode. During this mode, the frequency of the output clock signal is adjusted based on the frequency of the newly selected reference clock signal. After a designated period, the phase-locked loop circuit resumes its phase-locking operation.
