Abstract
A voltage regulator with hybrid adaptive voltage position includes a resistor, a controllable current source, a current DAC and an error amplifier. The resistor has a first terminal coupled to the output voltage of the voltage regulator and a second terminal. The controllable current source is coupled to the second terminal of the resistor to provide a main current proportional to the output current of the voltage regulator. The current DAC is configured to receive a digital signal and the output current, and provide a tuning current to the second terminal of the resistor based on the digital signal and the output current. The error amplifier generates a compensation signal based on a reference voltage and the voltage at the second terminal of the resistor, so as to adjust the output voltage of the voltage regulator.
