US Patent Issued to STMicroelectronics International on Sept. 29 for "Amplifier with temperature dependent gain and temperature compensated bandwidth" (Italian Inventors)

ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,750,011, issued on Sept. 29, was assigned to STMicroelectronics International N.V. (Geneva).

"Amplifier with temperature dependent gain and temperature compensated bandwidth" was invented by Danilo Karim Kaddouri (Pero, Italy), Francesco Borgioli (Leghorn, Italy), Roberto Pio Baorda (Casarile, Italy) and Lorenzo Ercolini (Milan).

According to the abstract* released by the U.S. Patent & Trademark Office: "An operational amplifier (OPAMP) is biased with a tail current that varies with temperature and process in order to compensate for variations in amplifier bandwidth. A proportional to absolute temperature (PTAT) current source generates a PTAT current producing a reference voltage. ...
