Title: The Innovations of Li-Lung Kao
Introduction
Li-Lung Kao is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of voltage regulators and signal amplifying circuits. With a total of 11 patents to his name, Kao continues to push the boundaries of technology.
Latest Patents
One of his latest patents is a voltage regulator that includes an error amplifier circuit, an output stage circuit, and an output feedback path. The error amplifier circuit consists of a first-stage amplifier and a second-stage amplifier. The first-stage amplifier is designed to amplify the difference between an output feedback signal and a reference signal, generating both a first differential signal and a second differential signal. The second-stage amplifier further amplifies the difference between these two signals to produce an output control signal. The output stage circuit, which is connected to a first power terminal, includes a switch that generates an output signal at an output node based on the output control signal. The output feedback path connects the output node to the error amplifier circuit, creating the output feedback signal based on the output signal.
Another notable invention is a circuitry applied to multiple power domains. This circuitry features an amplifier that includes an output stage and a switching circuit. The output stage consists of a first transistor and a second transistor, with the first transistor connected between a supply voltage and an output terminal, while the second transistor connects the output terminal to a ground voltage. The switching circuit is designed to select the body of the first transistor from either the supply voltage or a reference voltage.
