Latest Patents

One of his latest patents is a frequency multiplier for phase rotation. This invention includes a first digitally controlled delay line (DCDL) that receives a first clock signal and generates a second clock signal by changing the phase of the first clock signal. Additionally, it features a multiplying delay-locked loop (MDLL) that generates a third clock signal by multiplying the frequency of the second clock signal. A DCDL calibration circuit is also included, which receives the second clock signal and generates a gain signal for adjusting the gain of the first DCDL, ensuring that the difference between the maximum delay and minimum delay of the first DCDL is substantially equal to the period of the third clock signal.

Another notable patent is related to a display device, driving circuit, and driving method. This invention provides a structure and driving circuit that allows overlap driving to improve the charging rate and fake data insertion driving. The method involves inserting a fake image between real images to prevent afterimages and enhance moving picture response time, facilitating the implementation of high resolution.
