Latest Patents

Hwa Su Koh holds a patent for "Recovery circuits and methods for the same." This patent describes a recovery circuit that includes a phase detector, a quadrant decision unit, a quadrant controller, a charge pump unit, and a phase interpolator. The phase detector compares the phase of input data with the phase of a current output clock to generate first up and down signals. The quadrant decision unit determines the phase location for the current output clock and outputs quadrant decision signals based on this phase location. The quadrant controller then outputs second up and down signals based on the first signals and the quadrant decision signals. The charge pump unit generates phase control voltages based on the second signals, while the phase interpolator selects clocks from multiple sources based on the quadrant decision signals to produce an output clock signal.
