Latest Patents

One of his 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 Phase-Locked Loop (PLL) that utilizes a multi-curve voltage-controlled oscillator (VCO). The calibration unit generates a curve-select value to the VCO, allowing for both 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 gain-adjustable VCO and employs a Look-Up Table (LUT) to optimize gain calibration during normal operation.
