ALEXANDRIA, Va., Dec. 2 -- United States Patent no. 12,487,622, issued on Dec. 2, was assigned to Realtek Semiconductor Corp. (Hsinchu, Taiwan).

"Voltage regulator and signal amplifying circuit" was invented by Li-Lung Kao (Hsinchu, Taiwan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A voltage regulator includes an error amplifier circuit, an output stage circuit and an output feedback path. The error amplifier circuit includes a first-stage amplifier and a second-stage amplifier. The first-stage amplifier is configured to amplify a difference between an output feedback signal and a reference signal to generate a first differential signal and a second differential signal. The second-stage amplifier is conf...
