US Patent Issued to Texas Instruments on July 22 for "Gain and temperature tolerant bandgap voltage reference" (Arizona Inventors)

ALEXANDRIA, Va., July 23 -- United States Patent no. 12,366,877, issued on July 22, was assigned to Texas Instruments Inc. (Dallas).

"Gain and temperature tolerant bandgap voltage reference" was invented by Sudheer Gangula (Tucson, Ariz.), Jerry Doorenbos (Tucson, Ariz.) and Dimitar Trifonov (Vail, Ariz.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Examples of bandgap circuits and elements thereof enable generation of an accurate and stable bandgap reference voltage that is not affected by low current gain. An example circuit includes first and second input transistors, each having an emitter to receive a tail current; first and second core transistors, a collector of each coupled to ground; a first lower ...
