Abstract
Aspects of the disclosure provide a regulator circuit including an output circuit, an error detection circuit and an intermediate circuit. The output circuit is configured to receive a first supply voltage, output and regulate a second supply voltage based on a control signal. The error detection circuit is responsive to the first supply voltage, and is configured to compare the second supply voltage with a reference voltage, and generate an error signal with a voltage level that is indicative of a difference between the second supply voltage and the reference voltage. The intermediate circuit is configured to generate a first electrical current based on the error signal and a second electrical current based on the second supply voltage, combine the first electrical current and the second electrical current to generate a third electrical current, and generate the control signal at least partially based on the third electrical current.
