Abstract
In a voltage regulator including an error amplifier to generate a first signal related to an output voltage of the voltage regulator, a current sense circuit to generate a second signal related to an inductor current of the voltage regulator, and a PWM comparator to generate a PWM signal in response to the first and second signals to regulate the output voltage, a current feed-through adaptive voltage position control comprises supplying ramp signal and offset signal to modify the PWM signal to thereby eliminate the offset of the output voltage.
