Abstract:
An apparatus has a comparator circuitry (e.g., auto-zero comparator) with a first input, a second input, a third input; and an output; a first device (e.g., a low-side switch) coupled to the first and second inputs of the comparator; and a circuitry (e.g., a self-tuning logic) to generate a digital code which represents a comparator offset adjustment with reference to detection of current through a second device (e.g., an inductor), wherein the digital code (e.g., a multibit digital signal) is provided to the third input of the comparator circuitry.
