With a total of 4 patents to his name, his work showcases a blend of creativity and technical expertise.

Latest Patents

One of Yunlong Li's latest patents is titled "Fast coarse tune and fine tune calibration for a synthesizer by multi-curve calibration within a target window." This invention involves a PLL that utilizes a multi-curve voltage-controlled oscillator (VCO) with a curve-select input. The calibration unit generates a curve-select value to the VCO, allowing for efficient coarse and fine calibration. The process reduces calibration time by focusing on a limited number of curves within a smaller target window.

Another notable patent is "Gain calibration for direct modulation synthesizer using a look-up table searched by a reduced count from an overflow counter." This invention features a two-point modulation PLL with a gain-adjustable VCO. During calibration, the VCO output pulses are counted, and a gain calibration value is derived from a Look-Up Table (LUT). This innovative approach enhances the performance of the synthesizer while streamlining the calibration process.
