Latest Patents
One of Tsung-Kai Kao's key patents is titled "Segmented Fractional-N PLL." This invention includes a phase frequency detector module that receives a first clock and a second clock associated with a feedback path arrangement. The design features a coarse phase adjustment module that processes a coarse phase component and an output signal from a divider module in the feedback path. This module performs a coarse phase adjustment to enhance signal integrity. Additionally, a fine phase adjustment module utilizes a fine phase component and the coarse phase adjustment to produce the second clock. This innovative approach effectively cancels quantization noise during the coarse phase adjustment, significantly reducing the net phase noise of the divider module. A segmentation module generates the necessary control signals for both the coarse and fine phase components, ensuring optimal performance.
