Latest Patents

Kang's latest patents include innovative designs for phase locked loops. The first patent, titled "Phase locked loop for reducing fractional spur noise," describes a PLL that generates an output clock signal corresponding to a reference clock signal. This PLL features a first phase interpolator and a second phase interpolator, which work together to control the frequency of the output clock signal by multiplexing the interpolator clock signals.

The second patent, "Phase locked loop and operating method thereof," outlines a PLL that also generates an output clock signal based on a reference clock signal. This design includes a divider for generating a divided clock signal and a time-pulse converter that creates a time-pulse conversion signal. The digitally controlled oscillator, which incorporates an LC resonance circuit, is responsible for generating the output clock signal, with its frequency controlled according to the time-pulse conversion signal.
