US Patent Issued to STMicroelectronics International on Feb. 3 for "Offset calibration for an analog front-end system variable-gain amplifier" (Indian Inventors)

ALEXANDRIA, Va., Feb. 3 -- United States Patent no. 12,542,559, issued on Feb. 3, was assigned to STMicroelectronics International N.V. (Geneva).

"Offset calibration for an analog front-end system variable-gain amplifier" was invented by Ankur Bal (Greater Noida, India) and Anubhuti Chopra (Delhi, India).

According to the abstract* released by the U.S. Patent & Trademark Office: "Offset calibration for an analog front-end system is provided. The analog front-end system includes a variable-gain amplifier, and the calibration mitigates an offset error of the variable-gain amplifier. Calibration is based on a difference-based estimation technique combined with digital iteration. Difference-based estimation includes measuring different digita...
