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.
