Abstract
In a low-gain current-mode voltage regulator having a PWM comparator in response to the varying output voltage and inductor current of the voltage regulator to produce a PWM signal to regulate the output voltage, an offset signal is derived from a subtraction between the inputs of the PWM comparator, and the offset signal is injected into the PWM comparator to cancel the output offset of the voltage regulator.
