US Patent Issued to STMicroelectronics International on Sept. 15 for "Current equalization circuitry for the folded branch of a rail-to-rail input ota with ab-class output stage" (Italian Inventor)

ALEXANDRIA, Va., Sept. 15 -- United States Patent no. 12,738,909, issued on Sept. 15, was assigned to STMicroelectronics International N.V. (Geneva).

"Current equalization circuitry for the folded branch of a rail-to-rail input ota with ab-class output stage" was invented by Lorenzo Giancristofaro (Milan).

According to the abstract* released by the U.S. Patent & Trademark Office: "Described herein is an operational transconductance amplifier (OTA) with a constant current source that provides a constant current to a node. The OTA includes two input pairs of transistors: the first sources variable currents based on feedback and input voltages, while the second sinks variable currents also based on feedback and input voltages. A folded casco...
