Latest Patents

One of Liang Chang's latest patents focuses on methods and systems for controlling frequency and phase variations for PLL reference clocks. This application is directed to frequency controlling in an electronic device that includes a selector, a clock generator, and a controller. The selector chooses between a first reference signal and a second reference signal as an input signal with a specific input phase. The clock generator receives this input signal and generates a periodic signal that matches the input phase. When the first reference signal is selected, the controller identifies a temporal range that includes a peak instant when the second reference signal reaches peak frequency. It then selects a switching instant within this range based on the known temporal position of the peak instant and controls the selector to switch to the second reference signal at the appropriate time.
