US Patent Issued to TEXAS INSTRUMENTS on July 21 for "Auto zero techniques for high voltage analog front-end with robust AC common-mode rejection" (Texas, California Inventors)

ALEXANDRIA, Va., July 21 -- United States Patent no. 12,689,342, issued on July 21, was assigned to TEXAS INSTRUMENTS Inc. (Dallas).

"Auto zero techniques for high voltage analog front-end with robust AC common-mode rejection" was invented by Chienyu Huang (Dallas), Peng Cao (Dallas) and Kevin Scoones (Santa Clara, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The techniques and circuits, described herein, include solutions for auto-zeroing in auto-zero amplifiers in the presence of high frequency alternating current (AC) noise. In some aspects, first and second inputs of an auto-zero amplifier are coupled to a differential voltage with high AC noise. During an auto-zero phase, a first switching netw...
