US Patent Issued to Microsoft Technology Licensing on April 21 for "Phase-locked loops (PLL) including digitally controlled oscillator (DCO) gain calibration circuits and related methods" (North Carolina Inventors)

ALEXANDRIA, Va., April 21 -- United States Patent no. 12,609,707, issued on April 21, was assigned to Microsoft Technology Licensing LLC (Redmond, Wash.).

"Phase-locked loops (PLL) including digitally controlled oscillator (DCO) gain calibration circuits and related methods" was invented by Ping Lu (Cary, N.C.), Bupesh Pandita (Cary, N.C.) and Minhan Chen (Cary, N.C.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Interfaces between clock domains of an integrated circuit (IC) depend on synchronization of phase-locked loops (PLLs) that generate clocks in the different domains and on how each PLL responds to jitter in a shared reference clock. The well-controlled same bandwidth (and loop dynamic) for those PLLs...
