US Patent Issued to STMicroelectronics International on Feb. 10 for "PLL with a controlled range of output frequency for MEMS gyroscope" (Texas Inventors)

ALEXANDRIA, Va., Feb. 11 -- United States Patent no. 12,549,186, issued on Feb. 10, was assigned to STMicroelectronics International N.V. (Geneva).

"PLL with a controlled range of output frequency for MEMS gyroscope" was invented by Yamu Hu (Allen, Texas), Naren Kumar Sahoo (Frisco, Texas), Pavan Nallamothu (Little Elm, Texas), Deyou Fang (Frisco, Texas) and David McClure (Carrollton, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "According to an embodiment, a phased-locked loop (PLL) circuit, within a gyroscope system, generates demodulation signals. It includes a phase frequency detector receiving gyroscope output, which compares a reference signal with a feedback signal to produce an error signal. A...
