US Patent Issued to Microchip Technology on Jan. 13 for "Phase lock circuit" (Canadian Inventors)

ALEXANDRIA, Va., Jan. 13 -- United States Patent no. 12,525,982, issued on Jan. 13, was assigned to Microchip Technology Inc. (Chandler, Ariz.).

"Phase lock circuit" was invented by Gary Qu Jin (Kanata, Canada) and Kamran Rahbar (Kanata, Canada).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase lock system includes a phase detector to detect a phase difference between a reference signal and the output of a controllable oscillator circuit. A loop filter may filter the output of the loop filter and an integrator may integrate the output of the loop filter. The integrator output may be added to the output of the loop filter and may be input to the controllable oscillator circuit and may modify at least one ...
