US Patent Issued to Silicon Laboratories on Feb. 10 for "PLL using a DCO period length feedback clock pulse to determine phase error and TDC gain" (Singaporean Inventor)

ALEXANDRIA, Va., Feb. 11 -- United States Patent no. 12,549,188, issued on Feb. 10, was assigned to Silicon Laboratories Inc. (Austin, Texas).

"PLL using a DCO period length feedback clock pulse to determine phase error and TDC gain" was invented by Sheng Jue Peh (Singapore).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase-locked loop (PLL) includes a digitally controlled oscillator (DCO) that generates a DCO output signal. A feedback divider is coupled to the DCO output signal, divides the DCO output signal, and generates a feedback clock signal. The feedback clock signal is generated as a pulse having a pulse width equal to one period of the DCO output signal. A time-to-digital converter (TDC) receive...
