Patent 11929717 was granted and assigned to Texas Instruments on March, 2024 by the United States Patent and Trademark Office.
An output stage of an operational amplifier includes a low voltage (LV) metal oxide semiconductor (MOS) device and a dynamic current limit circuit. An output current of the operational amplifier flows through the LV MOS device. The dynamic current limit circuit is configured to sense a drain voltage of the LV MOS device and increase a clamping voltage for the LV MOS device when the drain voltage of the LV MOS device is less than a threshold voltage.
