US Patent Issued to Airoha Technology on March 3 for "Phase-locked loop circuit using hybrid loop calibration scheme and adaptively updated lookup tables and associated clock generating method" (Taiwanese Inventors)

ALEXANDRIA, Va., March 3 -- United States Patent no. 12,567,864, issued on March 3, was assigned to Airoha Technology Corp. (Hsinchu City, Taiwan).

"Phase-locked loop circuit using hybrid loop calibration scheme and adaptively updated lookup tables and associated clock generating method" was invented by Heng-Chih Lin (Hsinchu City, Taiwan) and Shu-Yu Lin (New Taipei City, Taiwan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase-locked loop (PLL) circuit includes a PLL core circuit, at least one lookup table, and a control circuit. The PLL core circuit generates an output clock under an open-loop calibration phase and a closed-loop calibration phase. The control circuit loads PLL parameters that are deri...
