US Patent Issued to Silicon Laboratories on Nov. 25 for "Feedback divider in a PLL used as a phase/frequency detector" (Singaporean Inventor)

ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,251, issued on Nov. 25, was assigned to Silicon Laboratories Inc. (Austin, Texas).

"Feedback divider in a PLL used as a phase/frequency detector" was invented by Sheng Jue Peh (Singapore).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase-locked loop (PLL) uses a feedback divider to provide phase and frequency information for faster lock. The PLL includes a time to digital converter that generates first phase information indicative of a phase difference between a reference clock and a feedback clock. A digital filter receives the first phase information and generates an oscillator control signal used by an oscillator to generate an oscillator out...
