Abstract
A target voltage is compared to a feedback voltage from a switching voltage regulator circuit (e.g., constant on-time regulator). The output of this comparison is integrated by an analog integrator. The analog output of the integrator is input to a three-level comparator that determines whether a saturating digital counter will increase (e.g., increment), decrease (e.g., decrement), or hold a current value. The output of the counter is summed with a digital value that was used to generate the target voltage to generate an offset canceled digital value. The offset canceled digital value is converted to an analog offset canceled reference voltage by a digital-to-analog converter. The analog offset canceled reference voltage is provided to the switching voltage regulator as the target voltage for the feedback loop of the regulator.
